Key Features
- 500 mA output current with 0.23 V nominal dropout voltage for efficient low-dropout power conversion
- High PSRR provides clean regulated output by rejecting input ripple and noise for sensitive RF and analog circuits
- Wide 2.5 V to 16 V input voltage range accommodates diverse power rails from battery to regulated bus
Applications
The NCP5500DT50RKG is suited for powering noise-sensitive analog, RF, and mixed-signal circuits in portable devices, handheld equipment, and industrial systems where a clean regulated supply is essential. Its high PSRR ensures effective rejection of input ripple and switching noise, making it ideal for audio, sensor, and communication subsystems. The 500 mA current capability and compact 4-pin SMD package support standalone regulation and post-regulation after a DC-DC converter.

Frequently Asked Questions
What is the dropout voltage of the NCP5500DT50RKG, and how does it affect minimum input voltage requirements?
The NCP5500DT50RKG has a nominal dropout voltage of 0.23 V and a maximum of 0.7 V at full 500 mA load, meaning the input must exceed the regulated output voltage by at least 0.7 V to maintain regulation under worst-case temperature and load conditions.
What input voltage range does the NCP5500DT50RKG accept, and how effective is its PSRR at rejecting supply noise?
The NCP5500DT50RKG accepts input voltages from 2.5 V to 16 V (absolute maximum 18 V) and provides high PSRR, typically above 60 dB at 1 kHz, effectively suppressing power supply noise and ripple to protect sensitive analog and RF circuits from interference.
When should designers transition away from the NCP5500DT50RKG and which alternatives offer comparable performance?
Since the NCP5500DT50RKG is designated as obsolete by ON Semiconductor, engineers starting new designs should consider active-production alternatives with similar 500 mA output, high PSRR above 60 dB, and compatible input voltage range up to 16 V to ensure long-term component supply continuity.
