PS3120A
PS3120A is Low noise switched capacitor voltage doubler manufactured by PULAN.
Description
The PS3120A is a low noise switched capacitor voltage doubler. It produces a regulated output voltage from a 2.7V to 4.5V input. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PS3120A ideally suited for small, battery-powered applications. The PS3120A have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1μA. The PS3120A is available in the industry standard SOT-23-6L power packages.
