TPS7A0510PDBVT

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

The TPS7A0510PDBVT is a fixed-output low-dropout regulator from the Texas Instruments TPS7A05 series, housed in a 5-pin SOT-23 package. It provides a nominal output voltage of 1 V with a maximum continuous output current of 200 mA. The device operates within an input voltage range of 1.4 V to 5.5 V and maintains an ultralow quiescent current of 1 µA typical. It features excellent transient response, high output accuracy (1% typical), and includes active output discharge and foldback current limiting for enhanced system protection.

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

Verify the specific suffix 'VT' indicates tape-and-reel packaging configuration. Confirm the 'P' designation aligns with the required pinout and thermal pad specifications for your PCB layout. Ensure compatibility with the intended operating temperature range and verify RoHS compliance status prior to final procurement.

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

Select this component when a fixed 1 V rail is required with strict low-power constraints. The SOT-23-5 package offers a compact footprint suitable for space-constrained designs. Consider the 1 µA quiescent current for battery longevity and the 200 mA output capability for moderate load requirements.

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

This part belongs to the TPS7A05 family of ultra-small, low-quiescent-current LDOs. The family supports various fixed output voltages ranging from 0.8 V to 3.3 V. Other available packages include X2SON, DSBGA, and 3-pin SOT-23 variants, allowing designers to choose the optimal form factor based on thermal and spatial needs.
