Overview
The NXP LD6815TD/30P,125 is a low dropout regulator (LDO) with a fixed nominal output voltage of 3.0 V and a maximum output current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V. The device features a typical power supply rejection ratio (PSRR) of 75 dB at 1 kHz and a dropout voltage of 250 mV at full load. It includes an auto discharge function for rapid output voltage decay in shutdown mode. The component is housed in a TSOP5 (SOT753) plastic surface-mounted package.
Feature Summary
- Integrated pull-down switching transistor provides a low-ohmic output state during disabled mode for fast discharge
- High-level electrostatic discharge protection rated at 6 kV under the Human Body Model standard
- Ultra-high power supply rejection ratio capability ensures effective suppression of input noise and ripples
- Low quiescent current consumption in shutdown mode minimizes overall system power drain
Applications
- Smartphones
- Tablet PCs
- Mobile handsets
- Portable media players
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the 3.0 V output voltage and the 'P' designation indicating the pull-down auto-discharge feature. Ensure compatibility with the required SOT753 package dimensions and thermal characteristics for your PCB layout. Confirm that the ambient temperature range meets your application's operational requirements.
Selection Notes
Select this component when a stable 3.0 V rail is required from varying input sources between 2.3 V and 5.5 V. The pull-down feature is critical if rapid output discharge is necessary upon disabling the regulator. Consider the 150 mA current limit and the need for external capacitors with appropriate ESR values to maintain stability and meet noise specifications.
Part Context
This part belongs to the LD6815 series of small-size low dropout regulators manufactured by NXP Semiconductors. The series utilizes monolithic silicon technology and is designed for portable electronics requiring high PSRR and compact footprints. The 'xxP' variant specifically denotes devices equipped with an internal pull-down transistor for enhanced shutdown performance compared to the high-ohmic 'xxH' variants.
Replacement Considerations
LD6815TD/30H,125: Offers identical electrical parameters but lacks the auto-discharge pull-down transistor, resulting in a high-ohmic output state when disabled.
