TPL905225-S5TR-S

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

The TPL905225-S5TR is a fixed-output low-dropout linear regulator from the 3PEAK TPL9052 series, providing a stable 2.5V output with a maximum continuous current of 500mA. It operates within an input voltage range of 1.75V to 5.5V and features ultra-low noise characteristics, specifically 8.6uVrms, making it suitable for sensitive analog circuits. The device offers high power supply rejection ratios (PSRR), reaching up to 88dB at 10kHz, and maintains an output accuracy of ±2.5% across line, load, and temperature variations. Packaged in SOT23-5, it supports stability with ceramic capacitors as small as 1uF.

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

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for SOT23-5 packages. Confirm that the selected variant meets the required output voltage tolerance and operating temperature range for the target application environment.

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

Select this component when designing circuits that demand minimal output noise and high PSRR for sensitive signal chains. It is appropriate for systems where input voltage varies but requires a stable, precise reference or analog rail. Consider the 500mA current capability and the requirement for at least 1uF ceramic output capacitance for stability during design validation.

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

This part belongs to the TPL9052 family of low-dropout regulators manufactured by 3PEAK. The series is characterized by its focus on high PSRR and ultra-low noise specifications, distinguishing it from standard LDOs. The TPL905225 variant specifically provides a fixed 2.5V output, catering to applications needing precise voltage references or analog power rails within the broader portfolio of adjustable and fixed output options.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements within the same series include other TPL9052 variants with different fixed output voltages if the system architecture allows voltage adjustment. Cross-referencing with similar ultra-low noise LDOs from other manufacturers requires verifying equivalent PSRR, noise density, and stability capacitor requirements.
