Dropout regulator
Vishay Intertechnology today announced two new 150-mA low-noise low-dropout regulators with the highest available current density in the small five-pin SC-70 package.
today announced two new 150-mA low-noise low-dropout (LDO) regulators with the highest available current density in the small five-pin SC-70 package.
Vishay claims their 2mm by 2mm footprint makes them well suited for use in battery-powered equipment such as cell phones, PDAs, pagers, digital cameras, MP3 players, cable and DSL modems, and other noise-sensitive electronics.
Under a 150mA load condition, the SiP21101 and SiP21102 feature a low dropout of 130mV and a ground current of 110µA, helping to prolong battery life in low-voltage portable electronic systems.
Designed to maintain regulation while delivering 300-mA peak current, the new ICs both feature a fast start-up time of 50µs, making them a salient choice for systems that have a high surge current upon turn-on. Fifteen fixed output voltage options ranging from 1.2V to 5.0V are available.
The SiP21101 can be used as pin-for-pin replacement, with significantly improved current handling, for the MAX8510 and MIC5253.
