PST73125B Datasheet | PowerSilicon

Description The PST731xx B family of low-dropout (LDO), low-power linear regulators offers high power supply rejection ratio (PSRR) while maintaining very low 35A ground current. The family uses an advanced CMOS process and a PMOSFET pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The PST731xx B is stable with a 1.0F ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations. It is fully specified from TJ = - 40°C to +125°C and is offered in a small TSOT23-5 package, a tiny SC70-5 package, and a ultra-small 2mm × 2mm DFN package with a thermal pad, which are ideal for small form factor portable equipment such as wireless handsets and PDAs. The PST731xx B is available in standard fixed output voltages of 1.2V (PST73112B), 1.5V (PST73115B), 1.8V (PST73118B), 2.5V (PST73125B), 2.8V (PST73128B), 3.0V (PST73130B), 3.3V (PST73133B), and custom voltage options (50m V step options between 0.8V and 5.0V are available upon request). - Features - Wide Input Voltage Range: 2.5V to 6.0V - Up to 300m A Load Current - Standard Fixed Output Voltage Options: 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, and 3.3V - Other Output Voltage Options Available on Request - Very Low IQ: 35µA - Ultra Low Dropout: 190m V at 300m A Load - High PSRR: 65db at 100Hz - Ultra-Fast Start-Up Time: 25µs - Excellent Load/Line Transient Response - Line Regulation: 0.03% typical - Load Regulation: 0.1% typical - Stable With 1µF Output Capacitor and Full Load Range (0 to 300m A) - Short Circuit and Overcurrent Protection - Thermal Shutdown Protection - 5k V HBM ESD Protection - Typical Application Diagram Vin IN - Ambient Temperature Range: -40ºc To 85°C - TSOT23-5, SOT23-5,SC70-5, and DFN package - Applications - Smart Phones and Cellular Phones - PDAs - MP3/MP4 Player - Digital Still Cameras - Portable instruments - Pin...
