Low-Input-Voltage, 300mA LDO Regulators
with RESET in SOT and TDFN
3/MX1976A
General Description
Features
The MAX1963A/MAX1976A low-dropout linear regula-
tors 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 (MAX1963A%
or 70ms (MAX1976A% after the output voltage reaches
regulation. These devices are offered in thin SOT23 and
thin DFN packages. An internal pMOS pass transistor
allows the low supply current to remain independent of
load and dropout voltage, making these devices ideal for
portable battery-powered equipment.

primarily for battery-powered applications. These devices

output voltages from +0.75V to +3.0V. As illustrated in

J
Operating Region and Power Dissipation
The MAX1963A/MAX1976A maximum power dissipa-
tion depends on the thermal resistance of the IC pack-
age and circuit board, the temperature difference
between the die junction and ambient air, and the rate
of airflow. The power dissipated in the device is P =
The reference is connected to the error amplifier, which
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.

designs using pnp pass transistors, p-channel
MOSFETs require no base drive, which reduces quies-
cent current. The pnp-based regulators also waste con-
siderable current in dropout when the pass transistor
saturates and use high base-drive currents under large
loads. The MAX1963A/MAX1976A do not suffer from
these problems and consume only 90µA (typ) of quies-
cent current under heavy loads, as well as in dropout.

heatsinking, expand the copper connected to the

The MAX1963A/MAX1976A deliver up to 300mA and
operate with an input voltage up to +3.6V. However,
when using the 6-pin SOT23 version, high output cur-
rents can only be sustained when the input-output dif-
ferential voltage is less than 2V, as shown in Figure 2.
Shutdown
Pull SHDN low to enter shutdown. During shutdown, the
output is disconnected from the input, an internal 1.5kΩ
resistor pulls OUT to GND, RESET is actively pulled
low, and the supply current drops below 1µA.
The maximum allowed power dissipation for the 6-pin
TDFN is 1.951W at T = +70°C. Figure 3 shows that the

by the TDFN package power rating.

Noise, PSRR, and Transient Response
The MAX1963A/MAX1976A are designed to operate
with low dropout voltages and low quiescent currents in
battery-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.

shift from the output impedance due to the load-current
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
MAX1963A/MAX1976A use a p-channel MOSFET pass
transistor, the dropout voltage is a function of drain-to-
