Low-Input-Voltage, 300mA LDO Regulators
with RESET in SOT and TDFN
General Description
Features
The MAX1963/MAX1976 low-dropout linear regulators
operate from a +1.62V to +3.6V supply and deliver a
guaranteed 300mA continuous load current with a low
100mV dropout. The high-accuracy ( 0.ꢀ5% output
voltage is preset to an internally trimmed voltage in the
+0.7ꢀV to +3.0V range. An active-low, open-drain reset
output remains asserted for at least 2.2ms (MAX1963%
or 70ms (MAX1976% after the output voltage reaches
regulation. These devices are offered in 6-pin thin
SOT23 and 6-pin 3mm x 3mm thin DFN packages.

o Supplc Current Independent of Load and
Dropout Voltage
An internal PMOS pass transistor allows the low supply
current to remain independent of load and dropout volt-
age, making these devices ideal for portable battery-pow-
ered equipment such as personal digital assistants
(PDAs%, cell phones, cordless phones, and notebook com-
puters. Other features include logic-controlled shutdown,
short-circuit protection, and thermal-overload protection.

Detailed Description
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 MAX1963/MAX1976 are low-dropout, high-accuracy,
low-quiescent-current linear regulators designed primarily
for battery-powered applications. These devices supply
loads up to 300mA and are available with preset output
voltages from +0.75V to +3.0V. As illustrated in Figure 1,
the MAX1963/MAX1976 consist of a reference, an error
amplifier, a P-channel pass transistor, an internal feed-
back voltage-divider, and a power-good comparator.

P-channel MOSFET pass transistor. Unlike similar
designs using PNP pass transistors, P-channel
MOSFETs require no base drive, which reduces quies-

saturates and use high base-drive currents under large
loads. The MAX1963/MAX1976 do not suffer from these
problems and consume only 90µA (typ) of quiescent

Thermal-Overload Protection
Thermal-overload protection limits total power dissipa-
tion in the MAX1963/MAX1976. When the junction tem-
perature exceeds T = +165°C, a thermal sensor turns

off the pass transistor, allowing the IC to cool. The ther-
mal sensor turns the pass transistor on again after the
junction temperature cools by 15°C, resulting in a
pulsed output during continuous thermal-overload con-
ditions. Thermal-overload protection safeguards the
MAX1963/MAX1976 in the event of fault conditions. For

The MAX1963/MAX1976 deliver up to 300mA and oper-
ate with an input voltage up to +3.6V. However, when
using the 6-pin SOT23 version, high output currents
can only be sustained when the input-output differential
voltage is less than 2V, as shown in Figure 2.
change, and the transient response. A typical transient
response for a step change in the load current from 20mA
to 200mA is 20mV. Increasing the output capacitor’s value
and decreasing the ESR attenuates the overshoot.
Input-Output (Dropout) Voltage
A regulator’s minimum input-output voltage difference
(dropout voltage) determines the lowest usable supply
voltage. In battery-powered systems, this determines the
useful end-of-life battery voltage. Because the
MAX1963/MAX1976 use a P-channel MOSFET pass tran-
sistor, the dropout voltage is a function of drain-to-source
The maximum allowed power dissipation for the 6-pin
TDFN is 1.951W at T = +70°C. Figure 3 shows that the
A
maximum input-output differential voltage is not limited
by the TDFN package power rating.

The output capacitor’s equivalent series resistance
(ESR) affects stability and output noise. Use output
capacitors with an ESR of 30mΩ or less to ensure sta-
bility and optimize transient response. Surface-mount
ceramic capacitors have very low ESR and are com-

Noise, PSRR, and Transient Response
The MAX1963/MAX1976 are designed to operate with
low dropout voltages and low quiescent currents in bat-
tery-powered systems while still maintaining good
noise, transient response, and AC rejection. See the
Typical Operating Characteristics for a plot of Power-
Supply Rejection Ratio (PSRR) versus Frequency.
When operating from noisy sources, 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.
