Overview
The MIC5156YM-TR is a Super LDO Regulator Controller in an 8-pin SOIC package. It operates from a supply voltage of 3V to 36V with a typical operating current of 4.5mA and shutdown current under 1µA. The device features an adjustable output range of 1.3V to 36V, controlled via external resistors connected to the EA pin. It includes an internal gate-to-source protective clamp rated at 16.6V and supports optional constant-current limiting with a threshold of 35mV.
Feature Summary
- Requires external N-channel MOSFET for high-current regulation
- Includes open-collector flag output for out-of-regulation detection
- Features TTL-compatible enable control for shutdown mode
Applications
- Ultrahigh current ultralow dropout voltage regulator
- Low noise/low-dropout SMPS post regulator
- High-current, current-limited switch
Procurement Notes
Verify that the ordering suffix -TR indicates tape-and-reel packaging rather than tube packaging. Confirm the specific manufacturer documentation matches the intended application requirements. Ensure the component meets all environmental compliance standards required by the final product design specifications.
Selection Notes
Select this controller when an external power MOSFET is preferred for high-current handling. Use this part for applications requiring an adjustable output voltage between 1.3V and 36V. Consider the need for an external gate drive supply since this model lacks an internal charge pump unlike other family members.
Part Context
This component belongs to the MIC5156/5157/5158 family of Super LDO Regulator Controllers. Unlike the MIC5157 and MIC5158 which feature internal charge pumps, the MIC5156 requires an external gate drive supply voltage (VP) to enhance the external N-channel MOSFET. It is available in both DIP and SOIC packages.
Replacement Considerations
MIC5156YN serves as the through-hole equivalent in an 8-pin DIP package. MIC5157YM and MIC5158YM are compatible controllers that include internal charge pumps but utilize a 14-pin package.
