uP8806
Ultra Low Noise, Fast Response, High PSRR
300/500mA LowDropout Linear Regulator
Features
General Description
The uP8806 is an ultra low noise, fast response, high power Wide Input Voltage Range from 2.4 to 6V
supply rejection ratio (PSRR) low dropout regulator
Ultra Low Dropout Voltage: 300mV @ 300mA
specifically designed to continuously deliver up to 300mA
High Power Supply Rejection Ratio Up to 74dB
output current.Designed with a P-channel MOSFET series
@1kHz
pass transistor, the uP8806 yields extremely low dropout
Ultra Fast Response in Line/Load Transient
voltage (e.g. 300mV at 300mA).
Stable with 1uF Ceramic Output Capacitor
The uP8806 does not require a bypass capacitor, hence
Low Shutdown Current: < 1uA
Foldback Output Current Limit
High Output Accuracy
achieving the smallest PCB area. This device reduces
output voltage noise under 70uV(RMS) and improves PSRR
to 40dB at 100kHz.
The uP8806 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 4.75V with 0.1V
Per Step
Over-Temperature Protection
Other features include foldback overcurrent protection, quick
soft start, and overtemperature protection. The uP8806 is
available in fixed output voltage from 0.8V to 4.75V with
0.1V per step. The device comes in SC70 - 5L,SC82 - 4L,
(T)SOT23 - 3L/5L, SOT223 - 3L, WDFN1.6x1.6 - 6LSOT89
- 3L and TO252 - 3L packages.
