LD6836TD/12P,125

Overview

The LD6836TD/12P,125 is a fixed-output Low Dropout (LDO) regulator manufactured by NXP Semiconductors. It provides a nominal output voltage of 1.2 V with a maximum continuous output current rating of 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 90 mV at full load. It is housed in a small SOT753 surface-mounted plastic package. Key electrical characteristics include a low quiescent current of 0.1 µA in shutdown mode, an RMS output noise voltage of 30 µV across the 10 Hz to 100 kHz frequency band, and a Power Supply Rejection Ratio (PSRR) of 55 dB at 1 kHz.

Feature Summary

• Integrated pull-down switching transistor ensures a low-ohmic output state when disabled, providing an auto discharge function for rapid output voltage decay.

Applications

• Analog and digital interfaces requiring lower than standard supply voltages
• Mobile appliances such as smartphones and cordless telephones
• Digital still cameras and portable media players

Procurement Notes

Verify that the specific ordering suffix matches the required package type and output configuration. Confirm compliance with environmental standards such as RoHS and halogen-free requirements. Ensure the selected variant aligns with the necessary thermal management capabilities for the intended operating temperature range.

Selection Notes

Select this component when a compact solution with integrated output discharge is required. The SOT753 package suits space-constrained designs. Verify that the external capacitor meets the minimum capacitance and ESR specifications to ensure stability under all operating conditions.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators designed for portable applications. The series includes variants in WLCSP4 and SOT753 packages, offering both high-ohmic and pull-down output states. The 'P' suffix specifically denotes the inclusion of the internal pull-down transistor for active discharge.
