Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN
General Description
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
+0.75V 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.

Regulator Input. Supply voltage can range from +1.62V to +3.6V. Bypass IN
with at least a 1µF ceramic capacitor to GND (see the Capacitor Selection and
Regulator Stability section).——GNDGround. GND also functions as a heatsink. Solder to a large pad or circuit-
board ground plane to maximize SOT23 power dissipation.45GNDGround6SHDNActive-Low Shutdown Input. A logic-low reduces supply current to below 1µA.
Connect to IN or logic-high for normal operation.4RESET
Open-Drain, Active-Low Reset Output. RESET rises 3.2ms (MAX1963A) or
100ms (MAX1976A) after the output has achieved regulation. RESET falls
immediately if VOUT drops below 82.5% of its nominal voltage, or if the
MAX1963A/MAX1976A are shut down.23I.C.Internally Connected. Leave unconnected or connect to GND.11OUTRegulator Output. Sources up to 300mA. Bypass with a 4.7µF low-ESR
ceramic capacitor to GND.—2, 7N.C.No Connection. Not internally connected.—EPGround (TDFNs only). EP also functions as a heatsink. Solder EP to a large
