Overview
The LD6805K/12P,115 is a fixed positive Low Dropout (LDO) regulator providing a nominal output voltage of 1.2 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 dropout voltage of 250 mV at full load and delivers a Power Supply Rejection Ratio (PSRR) of 75 dB at 1 kHz. It incorporates an integrated pull-down switching transistor for auto-discharge functionality in shutdown mode, ensuring a low-ohmic output state. The component is housed in a DFN1010C-4 plastic package with dimensions of 1 x 1 x 0.55 mm.
Feature Summary
- Integrated pull-down switching transistor provides a low-ohmic output state during disabled mode for rapid discharge.
- High power supply rejection ratio of 75 dB at 1 kHz ensures effective suppression of input noise and ripples.
- Ultra-small DFN1010C-4 package facilitates component miniaturization for space-constrained portable designs.
- Low quiescent current in shutdown mode minimizes power consumption when the device is inactive.
Applications
- Smart phones and mobile phone handsets
- Digital still cameras
- Portable media players
Procurement Notes
Verify that the specific suffix '115' corresponds to the required packaging configuration as defined by NXP Semiconductors. Confirm the nominal output voltage matches the design requirement of 1.2 V. Ensure the selected variant aligns with the necessary shutdown behavior, specifically the auto-discharge function inherent to the 'P' series designation.
Selection Notes
Select this component for applications requiring a compact footprint and high noise immunity. The LD6805K/12P,115 is suitable where a low-ohmic output state upon shutdown is critical for system safety or performance. Consider the 150 mA current rating and 2.3 V minimum input voltage to ensure compatibility with the target power rail and load requirements.
Part Context
This part belongs to the LD6805 series of low-dropout regulators manufactured by NXP Semiconductors. The series is characterized by ultra-high PSRR and small size, making it ideal for powering analog and digital interfaces in mobile appliances. The 'P' suffix indicates the inclusion of an auto-discharge feature, distinguishing it from the 'H' series which offers a high-ohmic output state.
Replacement Considerations
LD6805K/12H,115: Offers identical electrical specifications but lacks the auto-discharge pull-down transistor, resulting in a high-ohmic output state when disabled.
