Professional supply AS1359-285 EB 1 - Single Channels per IC Positive Fixed Linear Voltage Regulator Evaluation Board

Product Descriptions

The AS1358/AS1359 are ultra-low-noise, low-dropout linear regulators specifically designed to deliver up to 150/300mA continuous output current, and can achieve a low 140mV dropout for 300mA load current. The LDOs are designed and optimized to work with low-cost, smallcapacitance ceramic capacitors.

An integrated P-channel MOSFET pass transistor allows the devices to maintain extremely low quiescent current (40µA).

The AS1358/AS1359 uses an advanced architecture to achieve ultra-low output voltage noise of 9µVRMS and a power-supply rejection-ratio of better than 80dB (up to 10kHz).

The AS1358/AS1359 requires only 1µF output capacitor for stability at any load. When the LDO is disabled, current consumption drops below 500nA.

The devices are available in a TSOT23 5-pin package
