TPS7A1010PYKAR

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

The TPS7A1010PYKAR is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It provides a fixed 1 V output with a maximum continuous current of 300 mA. The device operates within an input voltage range up to 3.3 V and features ultra-low quiescent current of 2.6 µA. It offers high power supply rejection ratio (PSRR) ranging from 60 dB at 1 kHz to 35 dB at 1.5 MHz. The regulator includes enable control, overcurrent protection, thermal shutdown, and under-voltage lockout (UVLO). It functions reliably across a junction temperature range of -40°C to +125°C and is housed in a compact 5-DSBGA package.

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

Verify the specific suffix PYKAR corresponds to the 5-DSBGA package and reel tape configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure ESD handling protocols are followed during storage and assembly due to the small form factor.

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

Select this component when a stable 1 V rail is required with minimal static power draw. It is suitable for applications where input voltage does not exceed 3.3 V. Consider the 300 mA output limit and dropout characteristics relative to load requirements. Evaluate thermal performance based on PCB copper area and ambient conditions.

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

This part belongs to the TPS7A10 series of ultra-low-noise, low-quiescent-current LDO regulators. The series is designed for portable applications demanding high PSRR and low power consumption. The TPS7A1010 variant specifically targets 1 V output needs within the family's operational constraints.

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

Check for direct pin-compatible alternatives within the TPS7A10 series offering different fixed voltages. Verify if other manufacturers provide equivalent 300 mA, 1 V LDOs with similar PSRR and package dimensions.
