The LD6816CX4/25H is a fixed-output Low Dropout Regulator (LDO) from NXP Semiconductors, providing a nominal output voltage of 2.5 V with a maximum continuous output current rating of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 45 mV at full load. The device incorporates high-ohmic (three-state) output behavior when disabled, distinguishing it from pull-down variants. Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 0.1 µA in shutdown mode, alongside a typical RMS output noise voltage of 30 µV across the 10 Hz to 100 kHz frequency band.
Verify the specific suffix 'H' confirms the high-ohmic output configuration rather than the auto-discharge function found in 'P' or 'CxxP' variants. Confirm package dimensions match the WLCSP4 footprint requirements for your PCB layout. Ensure external capacitors meet the minimum capacitance and ESR specifications to maintain stability under all operating conditions.
Select this component when a fixed 2.5 V rail is required with minimal board space constraints. The high-ohmic output feature makes it suitable for applications where the regulator must be electrically isolated from the load when inactive. Consider the thermal resistance characteristics if multiple devices are placed closely together on the same substrate.
This part belongs to the LD6816 series of ultra-low dropout regulators designed for portable consumer electronics. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. The 'CX4' designation indicates the Wafer-Level Chip-Scale Package format, which supports miniaturization in dense mobile designs.
LD6816CX4/25P
When the enable pin is low, the LD6816CX4/25H enters a high-ohmic (three-state) output state, effectively disconnecting the output from the internal regulator circuitry.
No, the LD6816CX4/25H does not include an auto-discharge function. This feature is only available in the LD6816CX4/xxP and LD6816CX4/CxxP variants.
