500 mA, µCap Ultra-Low Dropout Regulator with High PSRR  
Features  
General Description  
• Ultra-Low Dropout Voltage: 200 mV @ 500 mA  
• Input Voltage Range: 2.5V to 5.5V  
• Output Voltage:  
The MIC5319 is a high performance, 500 mA LDO  
regulator, with high PSRR and very low noise, with low  
ground current.  
Ideal for battery-operated applications, the MIC5319  
features 1% accuracy, very low dropout voltage  
(typically 200 mV @ 500 mA), and low ground current  
at light load (typically 90 µA). Equipped with a  
logic-compatible enable pin, the MIC5319 can be set  
into a zero-off-mode current state, typically drawing  
only 0.5 µA current when disabled.

2: Regulation is measured at constant junction temperature using low duty cycle pulse testing.  
3: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its  
nominal VOUT. For outputs below 2.5V, dropout voltage spec does not apply, as the part is limited by mini-  
mum VIN spec of 2.5V. There may be some typical dropout degradation at VOUT < 3V.  
4: For Adjustable option, VOUT = 3V for dropout specification.  
5: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of  
the load current plus the ground pin current.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable  
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the  
maximum allowable power dissipation will cause the device operating junction temperature to exceed the  
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

MIC5319  
A unique, quick-start circuit allows the MIC5319 to  
drive a large capacitor on the bypass pin without  
significantly slowing turn-on time.  
4.0  
4.1  
APPLICATION INFORMATION  
Enable/Shutdown  
The MIC5319 features an active-high enable pin that  
allows the regulator to be disabled. Forcing the enable  
pin low disables the regulator and sends it into a “zero”  
off-mode current state. In this state, the current  
consumed by the regulator is typically only 0.5 µA.  
Forcing the enable pin high enables the output voltage.  
The active-high enable pin uses CMOS technology and  
the enable pin cannot be left floating, as this may cause  
an undetermined state on the output.  
4.5  
No-Load Stability  
Unlike many other voltage regulators, the MIC5319 will  
remain stable and in regulation with no load. This is  
especially important in CMOS RAM keep-alive  
applications.  
4.6  
Adjustable Regulator Application  
Adjustable regulators use a two-resistor divider to  
multiply the reference voltage and to produce the  
desired output voltage.  
4.2  
Input Capacitor  
The MIC5319 is a high-performance, high bandwidth  
device. Therefore, it requires a well-bypassed input  
supply for optimal performance. A minimum 1 µF  
capacitor is required from the input-to-ground to  
provide stability. Low-ESR ceramic capacitors provide  
optimal performance at a minimum of space. Additional  
high-frequency capacitors, such as small-valued NPO  
dielectric-type capacitors, help filter out high-frequency  
noise and are good design practice in any RF-based  
circuit.  
The MIC5319 output voltage can be adjusted from  
1.25V to 5.5V by using two external resistors  
(Figure 4-1). The resistors set the output voltage based  
on the following equation:  
EQUATION 4-1:  
R1  
R2  
------  
VOUT = VREF 1 +  
Where:  
VREF = 1.25V  
4.3  
Output Capacitor  
The MIC5319 requires an output capacitor of 2.2 µF or  
greater to maintain stability. The design is optimized for  
use with low-ESR ceramic chip capacitors. High ESR  
capacitors may cause high-frequency oscillation. The  
output capacitor can be increased, but performance  
has been optimized for a 2.2 µF ceramic output  
capacitor and does not improve significantly with larger  
capacitance.

X7R/X5R dielectric-type ceramic capacitors are  
recommended because of their temperature  
performance. X7R-type capacitors change capacitance  
by 15% over their operating temperature range and are  
the most stable type of ceramic capacitors. Z5U and  
Y5V dielectric capacitors change value by as much as  
50% and 60%, respectively, over their operating  
temperature ranges. To use a ceramic chip capacitor  
with Y5V dielectric, the value must be much higher than  
an X7R ceramic capacitor to ensure the same  
minimum capacitance over the equivalent operating  
temperature range.

Thermal Considerations  
The MIC5319 is designed to provide 500 mA of  
continuous current in a very small TDFN package.  
Maximum ambient operating temperature can be  
calculated based on the output current and the voltage  
drop across the part. Given an input voltage of 3.3V,  
output voltage of 2.8V, and output current of 500 mA,  
the actual power dissipation of the regulator circuit can  
be determined using the equation:  
4.4  
Bypass Capacitor  
A
capacitor can be placed from the bypass  
pin-to-ground to reduce output voltage noise. The  
capacitor bypasses the internal reference. A 0.1 µF  
capacitor is recommended for applications that require  
low-noise outputs. The bypass capacitor can be  
increased, further reducing noise and improving  
PSRR. Turn-on time increases slightly with respect to  
bypass capacitance.  
2017 Microchip Technology Inc.  
DS20005876A-page 11  
MIC5319  
Therefore, a 2.8V application at 500 mA of output  
current can accept an ambient operating temperature  
of 101.75°C in a 2 mm x 2 mm TDFN package. For a  
full discussion of heat sinking and thermal effects on  
voltage regulators, refer to the “Regulator Thermals”  
section of Microchip’s Designing with Low-Dropout  
Voltage Regulators handbook.  
EQUATION 4-2:  
PD = VIN VOUT  IOUT + VIN IGND  
Because this device is CMOS and the ground current  
is typically <100 µA over the load range, the power  
dissipation contributed by the ground current is <1%  
and can be ignored for this calculation:  
EQUATION 4-3:  
PD = 3.3V – 2.8V  500mA = 0.25W  
To determine the maximum ambient operating  
temperature  
of  
the  
package,  
use  
the  
junction-to-ambient thermal resistance of the device  
and the following basic equation:  
EQUATION 4-4:  
T
JMAXTA  
-------------------------------  
=
PDMAX  
JA  
Where:  
TJ(MAX) = 125°C  
θJA = 93°C/W (for the TDFN package)  
Substituting 0.25W for PD(MAX) and solving for the  
ambient operating temperature will give the maximum  
operating conditions for the regulator circuit. The  
maximum power dissipation must not be exceeded for  
proper operation.  
EQUATION 4-5:

Note the following details of the code protection feature on Microchip devices:  
Microchip products meet the specification contained in their particular Microchip Data Sheet.  
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the  
intended manner and under normal conditions.  
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our  
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data  
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.  
Microchip is willing to work with the customer who is concerned about the integrity of their code.  
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not  
mean that we are guaranteeing the product as “unbreakable.”  
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our  
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts  
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.  
Information contained in this publication regarding device  
applications and the like is provided only for your convenience  
and may be superseded by updates. It is your responsibility to  
ensure that your application meets with your specifications.

OTHERWISE, RELATED TO THE INFORMATION,
