Overview
The LD6815TD/33H,125 is a fixed-output Low Dropout Regulator (LDO) from NXP Semiconductors with a nominal output voltage of 3.3 V. It operates within an input voltage range of 2.3 V to 5.5 V and supports a maximum output current of 150 mA. The device features a typical dropout voltage of 250 mV at full load and achieves a Power Supply Rejection Ratio (PSRR) of 75 dB at 1 kHz. It utilizes the SOT753 (TSOP5) surface-mounted package.
Feature Summary
- High-level ElectroStatic Discharge (ESD) protection rated at 6 kV Human Body Model
- Ultra-low quiescent current consumption in shutdown mode
- Overcurrent protection for circuit safeguarding
- High-ohmic state at the output pin when disabled
Applications
- Smartphones
- Tablet PCs
- Mobile handsets
- Portable media players
Procurement Notes
Verify the specific suffix 'H' indicates a high-ohmic output stage rather than a pull-down configuration. Confirm the '33' designation corresponds to the required 3.3 V nominal output voltage. Ensure the 'TD' prefix matches the specified SOT753 plastic package format. Validate that the '125' suffix aligns with the intended operating temperature requirements.
Selection Notes
Select this component for applications requiring stable power delivery with minimal voltage drop under load. The high PSRR makes it suitable for noise-sensitive circuits. Verify that the external capacitor ESR remains within the specified limits to ensure stability. Consider the thermal resistance characteristics if the ambient temperature approaches the upper operational limit.
Part Context
This part belongs to the LD6815 series of low dropout regulators designed for portable electronics. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'H' suffix distinguishes it from the 'P' variant by providing a high-ohmic output state instead of an auto-discharge function when the device is disabled.
Replacement Considerations
LD6815TD/33P,125 provides identical electrical performance but includes an auto discharge function.
