The ams-OSRAM USA INC. AS1357 is a triple-output, positive, programmable linear voltage regulator IC, capable of delivering up to 200mA per channel. This device features adjustable output voltages ranging from 1.8V to 3.3V, with a maximum input voltage of 5.5V. Its quiescent current is rated at 275µA, contributing to power efficiency. Protection features include over-current, over-temperature, and soft-start capabilities. The AS1357 offers excellent power supply ripple rejection (PSRR) of 70dB to 40dB across a 1kHz to 100kHz bandwidth. Control is managed via an enable pin. The AS1357 is housed in a 12-QFN (4x4) package, suitable for surface mounting, and is supplied in trays. This component finds application in areas such as portable electronics and battery-powered devices.
