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

Direct substitutes within the same series include S-1132B36-U5T1G (SOT-89-5 package) and S-1132B36-I6T2U (SNT-6A(H) package). Verify pinout compatibility and thermal characteristics when transitioning between different package types.

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

How does the ON/OFF pin function for the 'B' product type?

For the 'B' product type, the ON/OFF pin uses positive logic. Setting the pin to a high level turns the regulator ON, while setting it to a low level turns it OFF, significantly reducing current consumption.

What are the recommended external components for stability?

The datasheet recommends using ceramic capacitors of 0.1 μF or more for both input (CIN) and output (CL). The equivalent series resistance (ESR) of the output capacitor should be 2.0 Ω or less.
