Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AS1358-BTTT-27

AS1358-BTTT-27

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1358-BTTT-27 is a low-dropout linear regulator delivering a fixed 2.7V output with a maximum continuous load current of 150mA. It operates within an input voltage range of 2V to 5.5V and achieves a typical dropout voltage of 95mV at full load. The device features ultra-low output noise of 9µVRMS and high power-supply rejection ratio exceeding 80dB up to 10kHz. Quiescent current is maintained at 40µA, dropping below 500nA in shutdown mode. It utilizes a TSOT23 5-pin package and requires only 1µF ceramic capacitors for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering code AS1358-BTTT-27 against manufacturer documentation to confirm the 2.7V preset output and 150mA current rating. Ensure compatibility with the required TSOT23 5-pin surface-mount footprint during procurement planning. Confirm RoHS compliance status through official datasheets prior to finalizing supply chain agreements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when designing space-constrained portable systems requiring stable 2.7V rails. It is suitable for applications needing minimal quiescent current draw and high power-supply rejection. Verify that the input voltage remains above the minimum dropout threshold relative to the 2.7V output under all expected load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AS1358/AS1359 series of ultra-low-noise LDOs from ams OSRAM. The AS1358 variant specifically provides 150mA output capability, distinguishing it from the higher-current AS1359 model. Both share identical architectural features including the P-channel pass transistor and noise reduction capabilities.
