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.

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-W 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-mA 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).
