AS1358 Datasheet (austriamicrosystems AG) - (AS1358 / AS1359) High-PSRR Low Dropout Regulators

AS1358, (AS1358 / AS1359) High-PSRR Low Dropout Regulators

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.
