Overview
The LD6836TD/23H,125 is a Low Dropout regulator (LDO) from the LD6836 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 2.3 V with a maximum 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 utilizes a small SOT753 Surface-Mounted Device plastic package. Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 0.1 µA in shutdown mode. The component includes integrated over-temperature protection and output current limiting.
Feature Summary
- Ultra low dropout performance with minimal voltage drop at high current loads
- Low noise operation suitable for sensitive analog and digital interfaces
- High-ohmic output state when disabled for efficient power management
- Integrated electrostatic discharge protection up to 10 kV Human Body Model
Applications
- Analog and digital interfaces requiring lower supply voltages in mobile appliances
- Smartphones and mobile phone handsets
- Digital still cameras and portable media players
- Personal navigation devices and mobile internet devices
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component for applications requiring a stable 2.3 V rail from a variable input source between 2.3 V and 5.5 V. The SOT753 package is suitable for space-constrained designs. Ensure external capacitors meet the minimum ESR requirements for stability. Consider the high-ohmic output behavior if interfacing with other active circuits that require isolation during shutdown states.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators designed for portable electronics. The series offers various fixed output voltages and packaging options, including WLCSP and SOT753. The 'H' suffix denotes a high-ohmic output state upon disable, distinguishing it from 'P' variants which feature an auto-discharge function. The series is optimized for low power consumption and miniaturization in consumer mobile devices.
Replacement Considerations
Compatible substitutes within the same family include LD6836TD/22H,125 and LD6836TD/25H,125, provided the different nominal output voltages align with system requirements. Verify pin compatibility and thermal characteristics when transitioning between variants.
