TLV73312PDQNR3

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

The TLV73312PDQNR3 is a fixed-output low-dropout linear regulator from Texas Instruments, providing a stable 1.2 V output with a maximum current capacity of 300 mA. It operates within an input voltage range of 1.4 V to 5.5 V and maintains a typical quiescent current of 34 µA. The device features a dropout voltage as low as 125 mV at full load and offers high power supply rejection ratio performance. Packaged in a compact 4-X2SON (1x1) surface-mount format, it supports junction temperatures from -40°C to +125°C.

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

Verify the specific suffix 'R3' corresponds to the reel packaging configuration when ordering. Confirm that the 4-X2SON package dimensions align with your PCB footprint requirements. Ensure input voltage does not exceed the 5.5 V absolute maximum rating during operation.

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

Select this component for designs requiring minimal external components and small board space. It is suitable for applications where low noise and high PSRR are critical. Consider the 1.2 V fixed output constraint and verify that the input voltage remains above the minimum threshold under all operating conditions.

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

This part belongs to the TLV733P family of low-dropout regulators designed for space-constrained, battery-operated systems. The series emphasizes low IQ and capacitor-free operation to simplify circuit design. The PDQNR3 variant specifically denotes the X2SON package with tape-and-reel shipping.

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

Direct pin-to-pin replacements within the same family include TLV73318PDQNR3 (1.8 V output) and TLV73315PDQNR3 (1.5 V output). Verify that the alternative voltage setting meets system requirements before substitution.
