Technical Details & Description

1.5V fixed LDO for automotive power rails

The STMicroelectronics LDK130M15R is a single-output, positive fixed linear regulator delivering 1.5 V at up to 300 mA.

The LDK130M15R comes in a SOT-23-5 package. It is a surface-mount part with an enable pin for shutdown control.

Protection features for harsh environments

Built-in over-current and over-temperature protection cover the common fault conditions in automotive and industrial applications — a shorted load on the output or a hot engine bay during summer operation. These are self-recovering protections; the regulator shuts down and restarts once the fault clears.

It is a current-production part.

Frequently asked questions

Is LDK130M15R AEC-Q100 qualified?

Yes, it is part of the Automotive AEC-Q100 series, qualified for automotive applications.

Is LDK130M15R RoHS compliant?

Yes, it is ROHS3 compliant.

Can LDK130M15R be used as a replacement for LDK130M12R?

The LDK130M12R outputs 1.2 V fixed; the LDK130M15R outputs 1.5 V fixed. They are pin-compatible in the same SOT-23-5 package but the output voltage differs — verify the target rail voltage before substituting.

What are alternatives to LDK130M15R?

The LD39020DTPU33R is a similar AEC-Q100 LDO but outputs 3.3 V at 200 mA with higher PSRR (80 dB at 1 kHz). The LDFP series offers an adjustable output up to 1 A with a 16 V input ceiling, but lacks the fixed 1.5 V option. Neither is a drop-in replacement — check output voltage, current, and package compatibility.
