uP8807
600mA Low Dropout Linear Regulator
Features
General Description
Wide Input Voltage Range from 2.5V to 5.5V
The uP8807 is a compact fast response low dropout
regulator specifically designed to continuously deliver up
to 600mA output current. Designed with a P-channel
MOSFET series pass transistor, the uP8807 yields
extremely low dropout voltage (e.g. 300mV at 600mA)
and maintains very low quiescent current (70uA).
Ultra Low Dropout Voltage: 300mV @ 600mA
Ultra Fast Response in Line/Load Transient
Stable with 1uF Ceramic Output Capacitor
Low Quiescent Current: 70uA Typical
Low Shutdown Current: < 1uA
The uP8807 does not require a bypass capacitor, hence
achieving the smallest PCB area. The uP8807 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.
Foldback Output Current Limit
High Output Accuracy
1.5% Initial Accuracy
Fixed Output Voltages: 0.8V to 3.3V
Adjustable Output Voltage from 0.8V to 5V
Other features include foldback overcurrent protection,
quick soft start, and over temperature protection. The
uP8807 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.
