150-mA Low-Noise LDO Regulator
With Error Flag and Discharge
DESCRIPTION
The SiP21102 is a 150 mA CMOS LDO (low dropout) voltage
regulator. It is the perfect choice for low voltage, low power
applications. An ultra low ground current makes this part
attractive for battery operated power systems. The SiP21102
also offers ultra low dropout voltage to prolong battery life in
portable electronics. Systems requiring a quiet voltage
source, will benefit from the SiP21102’s low output noise.
The SiP21102 is designed to maintain regulation while
delivering 300 mA peak current, making it ideal for systems
that have a high surge current upon turn-on.
For better transient response and regulation, an active pull-
down circuit is built into the SiP21102 to clamp the output
voltage when it rises beyond normal regulation. The
SiP21102 automatically discharges the output voltage by
connecting the output to ground through a 100
Ω n-channel
MOSFET when the device is put in shutdown mode.
The SiP21102 features reverse battery protection to limit
reverse current flow to approximately 1 A in the event
reversed battery is applied at the input, thus preventing
damage to the IC.
The SiP21102 is available in a lead (Pb)-free 5-pin SC70
package for operation over the industrial operating range
(- 40 °C to 85 °C).
