TLVH432CPK

Overview

The TLVH432CPK is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±1.5% and a temperature coefficient of 138 ppm/°C. It supports a cathode current range of 80 µA to 70 mA, with a maximum operating temperature of +125°C. Packaged in a 3-pin SOT-89 case, it is designed for surface-mount installation.

Feature Summary

Adjustable output voltage capability spanning from 1.24 V to 18 V
Low-voltage operation suitable for battery-powered applications
Wide operating current range supporting minimal load requirements

Applications

Battery-operated equipment requiring precise voltage monitoring
Portable instrumentation reference circuits
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'CPK' indicates the commercial temperature grade (0°C to 70°C) rather than the industrial grade (-40°C to 125°C). Confirm the pinout configuration matches the schematic, as reverse pinout variants exist within the family. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a compact SOT-89 package is required for space-constrained designs. Choose the CPK variant specifically if the application environment remains within the commercial temperature range. Verify that the 1.5% initial accuracy meets the system tolerance requirements compared to higher-precision alternatives.

Part Context

This part belongs to the TLVH432 series of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to standard bandgap references in portable electronics. The series offers various packages and accuracy grades to suit different power management needs.
