AS1358-BTTT-25

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

The AS1358-BTTT-25 is a low-dropout linear regulator delivering a fixed 2.5V output with a maximum continuous current of 150mA. It operates from an input voltage range of 2V to 5.5V and achieves a dropout voltage as low as 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-25 against manufacturer documentation to confirm the 150mA load rating and 2.5V preset output. Ensure compatibility with the required TSOT23 5-pin surface-mount footprint. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range and does not exceed absolute maximum ratings.

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

Select this component when designing space-constrained portable systems requiring stable power delivery under varying loads. The integrated P-channel pass transistor minimizes ground pin current compared to traditional designs. Verify that the input source can maintain the necessary headroom above the 2.5V output to prevent excessive dropout voltage during peak current demands.

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

This part belongs to the AS1358/AS1359 series of ultra-low-noise LDOs manufactured by austriamicrosystems AG. The series is engineered specifically for applications where power efficiency and signal integrity are critical. The AS1358 variant provides 150mA capacity, distinguishing it from the higher-current AS1359 model while sharing identical architectural benefits.
