Overview
The ATL432BIDBZR-S is a low quiescent current, adjustable precision shunt regulator from Texas Instruments. It operates within a voltage range of 2.5 V to 36 V and features an initial accuracy of ±0.5%. The device supports a maximum shunt current of 100 mA and utilizes a SOT-23-3 surface-mount package. It is designed for applications requiring precise voltage regulation with minimal power consumption.
Feature Summary
- Low quiescent current operation for energy efficiency
- Adjustable output voltage ranging from 2.5 V to 36 V
- High initial accuracy of ±0.5% at room temperature
- Compact SOT-23-3 surface-mount packaging
Applications
- Battery-powered portable devices
- Precision voltage reference circuits
- Linear and switching power supply regulation
- Temperature compensation networks
Procurement Notes
Verify the specific suffix '-S' against the official Texas Instruments datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets the required automotive or industrial grade standards if applicable. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status prior to integration into final assemblies.
Selection Notes
Select this component when high accuracy and low standby current are critical. The ±0.5% tolerance suits precision measurement systems. Compare thermal performance and package size against alternatives like TL432 variants. Consider the operating temperature range and input voltage limits relative to the target application environment.
Part Context
This part belongs to the ATL432 family of low-current shunt regulators. It shares functional similarities with the standard TL432 series but offers improved accuracy and lower quiescent current. The device serves as a drop-in replacement for Zener diodes in many regulation scenarios while providing superior stability and adjustability.
Replacement Considerations
The TL432AIDBZR is a compatible alternative with similar functionality. Verify pinout alignment between the -S suffix variant and standard DBZ packages before substitution.
