Overview
The TLVH432BCDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 1.24 V to 18 V and is housed in an SOT-23-3 surface-mount package. The device features an initial accuracy of ±0.5% and a temperature coefficient of 138 PPM/°C. It supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. The component functions across a temperature range of 0°C to +70°C.
Feature Summary
- Provides adjustable reference voltage output from 1.24 V to 18 V
- Ensures high precision with ±0.5% initial accuracy tolerance
- Designed for low-voltage applications with minimal power consumption
Applications
- Battery-powered portable devices requiring precise voltage monitoring
- Low-voltage power supply regulation circuits
- Portable instrumentation and measurement equipment
Procurement Notes
Verify the specific suffix DBZR corresponds to the SOT-23-3 tape-and-reel packaging configuration. Confirm that the commercial grade temperature range (0°C to +70°C) aligns with your operational environment requirements. Ensure compatibility with standard surface-mount assembly processes for the specified footprint.
Selection Notes
Select this component when a compact, low-cost solution is needed for voltages up to 18 V. The ±0.5% accuracy suits general-purpose references where higher precision is unnecessary. Consider the 70 mA sink capability for driving indicator loads or feedback networks in simple regulator topologies.
Part Context
This part belongs to the TLVH432 family of low-voltage shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering better stability and lower dynamic impedance. The SOT-23-3 package allows for space-constrained designs in consumer electronics and industrial control systems.
Replacement Considerations
The TLVH432BQDBZR is a qualified automotive-grade variant within the same series. Verify if extended temperature ranges or enhanced reliability standards are required before substituting.
