600mA Low Dropout Linear Regulator
uP0111
Features
General Description
The uP0111 is a compact fast response low dropout Wide Input Voltage Range from 2.5V to 5.5V
regulator specifically designed to continuously deliver up
to 600mA output current. Designed with a P-channel
Ultra Fast Response in Line/Load Transient
MOSFET series pass transistor, the uP0111 yields
Ultra Low Dropout Voltage: 300mV @ 600mA
Stable with 1uF Ceramic Output Capacitor
Low Ground Current: 70uA Typical
Low Shutdown Current: < 1uA
Foldback Output Current Limit
High Output Accuracy
extremely low dropout voltage (e.g. 300mV at 600mA) and
maintains very low ground current (70uA).
The uP0111 does not require a bypass capacitor, hence
achieving the smallest PCB area. The uP0111 is designed
and optimized to work with low-value, low-cost ceramic
capacitors. Only a 1uF ceramic output capacitor is required
for stable operation for any load conditions.
1.5% Initial Accuracy
Fixed Output Voltages: 0.8V to 3.3V
Adjustable Output Voltage from 0.8V to 4.5V
Other features include foldback overcurrent protection,
quick soft start, and overtemperature protection. The
uP0111 is available in fixed output voltage from 0.8V to
3.3V with 0.1V per step or as an adjustable device with a
0.8V reference voltage. The device comes in various
packages.
