GENERAL DESCRIPTION  
The LP3985A-XX family are very low-noise, very low-dropout, low  
quiescent-current linear regulators designed for battery-powered  
applications, although they can also be used for devices powered by  
AC-DC converters. The device is available in a preset output voltage  
of 2.6 V. Typical dropout voltages are only 165 mV at 150 mA and  
41 mV at 50 mA. Reverse battery current is extremely low, 0.5 µA  
typical.  
For demanding applications, output noise voltage of typically  
30 µV  
is achieved with a 0.01 µF capacitor on the BYPASS pin.  
rms  
The input voltage can vary from 2.5 to 6.5 V , providing up to  
dc  
WL-CSP5 (bottom view)  
SO5 (SOT23-5)  
150 mA output current.  
An internal P-channel FET pass transistor maintains an 85 µA  
typical supply current, independent of the load current and dropout  
voltage. Other features include a 0.01 µA logic-controlled shutdown,  
short circuit and thermal shutdown protection, and reverse battery  
protection. The LP3985A also includes an auto-discharge function  
which actively discharges the output voltage to ground when the  
device is placed in shutdown.  
To accommodate high density layouts, it is packaged in wafer-level  
chip-scale (WL-CSP), as well as SO5 (SOT23-5) packages.

TECHNICAL DISCUSSION  
The LP3985A-XX family are very low-noise, very low-dropout, low  
quiescent current linear regulators designed for battery-powered  
applications, although they can also be used for devices powered by  
AC-DC converters.  
The GND pin provides an electrical connection to ground and a path  
for heat transfer away from the junction. Connect the GND pin to  
ground using a large pad or ground plane to maximize heat transfer.  
Noise reduction  
The voltage regulation components of the LP3985A consist of a  
1.23 V reference, an error amplifier, a P-channel pass transistor, and  
an internal feed-back voltage divider. The device also contains a  
reverse battery protection circuit, a thermal sensor, a current limiter,  
An optional external 0.01 µF bypass capacitor at BYPASS, in  
conjunction with an internal 200 resistor, creates an 80 Hz  
low-pass filter for noise reduction. The LP3985A produces  
30 µV  
of output voltage noise with C  
= 0.01 µF and  
bypass  
RMS  
and shutdown logic.  
C
= 10 µF. This is negligible in most applications.  
OUT  
Voltage regulation  
Start-up time is minimized by a power-on circuit that pre-charges the  
bypass capacitor. The ‘Typical Performance Curves’ section shows  
graphs of ‘Output noise versus BP capacitance’ (Figure 16), ‘Output  
noise versus output current’ (Figure 17), and ‘Output noise spectral  
density versus frequency’ (Figure 13).  
The 1.23 V band-gap reference is connected to the error amplifier’s  
inverting input. The error amplifier compares this reference with the  
feedback voltage and amplifies the difference. If the feedback  
voltage is lower than the reference voltage, the pass-transistor gate  
is pulled lower, which allows more current to pass to the output and  
increases the output voltage. If the feedback voltage is too high, the  
pass-transistor gate is pulled up, allowing less current to pass to the  
output. The output voltage is fed back through an internal resistor  
Device protection  
The LP3985A has several built-in protection circuits.  
Current limiter: The current limiter controls the the pass transistor’s  
gate voltage so the output current cannot exceed 390 mA. We  
recommend using 160 mA minimum to 500 mA maximum in the  
design parameters. Because of the current limiter, the output can be  
shorted to ground for an indefinite amount of time with no damage to  
the part.  
voltage divider connected to the V  
pin.  
OUT  
The LP3985A uses a 1.0 typical P-channel MOSFET pass  
transistor. The P-channel MOSFET requires no base drive, therefore  
the device has lower quiescent current than a comparable PNP  
transistor-based design. The LP3985A-XX uses 100 µA of quiescent  
current under any load conditions.  
Reverse battery protection: The reverse battery protection circuit  
prevents damage to the device if the supply battery is accidentally

to ground  
SHDN  
IN  
and disconnects the device’s internal circuits if it detects reversed  
polarity. Reverse supply current is limited to 1 mA when this  
protective circuit is active, preventing the battery from rapidly  
discharging through the device.  
Power dissipation  
The LP3985A’s maximum power dissipation depends on the thermal  
resistance of the case and circuit board, the temperature difference  
between the die junction and ambient air, and the rate of air flow.  
Thermal overload protection: When the junction temperature  
exceeds +140 °C, the thermal sensor signals the shutdown logic to  
turn off the pass transistor. After the junction temperature has cooled  
by 15 °C the sensor signals the shutdown logic to turn the pass  
transistor on again. This will create a pulsed output during lengthy  
thermal overloads.  
The power dissipation across the device is P = I

APPLICATION INFORMATION  
Capacitor selection and regulator stability  
Normally, use a 1 µF capacitor on the LP3985A input and a 1 µF to  
10 µF capacitor on the output. To improve the supply-noise rejection  
and line-transient response, use input capacitor values and lower  
ESRs. To reduce noise and improve load-transient response,  
stability, and power-supply rejection, use use large output  
capacitors.  
Load-transient considerations  
The LP3985A load-transient response graphs (Figures 18, 19, and  
20) show two components of the output response: a DC shift from  
the output impedance due to the load current change, and the  
transient response. Typical transient for a step change in the load  
current from 0 mA to 50 mA is 40 mV. Increasing the output  
capacitor’s value and decreasing the ESR attenuates the overshoot.  
For stable operation over the full temperature range and with load  
currents up to 150 mA, a 1 µF (min.) ceramic capacitor is  
recommended.  
PSRR and operation from sources other than  
batteries  
The LP3985A is designed to deliver low dropout voltages and low  
quiescent currents in battery-powered systems. When operating  
from sources other than batteries, improved supply-noise rejection  
and transient response can be achieved by increasing the values of  
the input and output bypass capacitors, and through passive filtering  
techniques.  
Note that some ceramic dielectrics exhibit large capacitance and  
ESR variation with temperature. With dielectrics such as Z5U and  
Y5V, it may be necessary to increase the capacitance by a factor  
of 2 or more to ensure stability at temperatures below –10 °C. With  
X7R or X5R dielectrics, 1 µF should be sufficient at all operating  
temperatures for V  
= 2.5 V.  
OUT  
Power-supply rejection is 73 dB at low frequencies and rolls off  
above 10 kHz. See Figure 15, ‘Power supply rejection ratio versus  
frequency’.  
A graph of the Region of Stable C  
ESR versus Load Current is  
OUT  
shown in Figure 14. Use a 0.01 µF bypass capacitor at BYPASS for  
low output voltage noise. Increasing the capacitance will slightly  
decrease the output noise, but increase the start-up time. Values  
above 0.1 µF provide no performance advantage and are not  
recommended (see Figures 21 and 22 in the ‘Typical Performance  
Curves’ section).  
For output voltage greater than the minimum input voltage (2.5 V),  
the regulator’s minimum input-output voltage differential (or dropout  
voltage) determines the lowest usable supply voltage. In  
battery-powered systems, this will determine the useful end-of-life  
battery voltage. Because the LP3985A uses a P-channel MOSFET  
pass transistor, the dropout voltage is a function of drain-to-source  
on-resistance (R ) multiplied by the load current (see ‘Typical  
DS(ON)  
Performance Curves’).
