Key Features
- Ultra-low output noise enables clean negative supply rails for precision ADCs, op-amps, and RF circuits sensitive to power supply noise
- High PSRR across frequency rejects input ripple from switching pre-regulators, allowing direct post-regulation of negative rails without additional filtering
- Fixed -3.3 V output with 0.13 V nominal dropout voltage and 3.8 V to 5.5 V input range supports standard negative supply architectures in signal chain designs
Applications
The ADP7183ACPZN3.3-R7 is designed to supply negative voltage rails in precision analog signal chains, RF receiver front ends, and high-resolution ADC reference circuits where ultra-low noise is essential. Its high PSRR eliminates the need for additional LC filtering after a negative charge pump or inverting switching regulator, simplifying power supply architecture. It is also used in audio equipment, medical instrumentation, and test and measurement systems requiring a clean -3.3 V supply with minimal impact on sensitive analog performance.

Frequently Asked Questions
What is the output noise of the ADP7183ACPZN3.3-R7, and why does it matter for precision analog circuits?
The ADP7183ACPZN3.3-R7 delivers ultra-low output noise typically below 10 µV RMS in the 10 Hz to 100 kHz band. In precision 24-bit ADC and DAC designs, power supply noise directly corrupts the dynamic range; a 10 µV RMS noise floor translates to less than 0.5 LSB of noise contribution at 24-bit resolution on a 5 V full-scale input, preserving the converter's theoretical signal-to-noise ratio.
What input voltage range does the ADP7183ACPZN3.3-R7 accept, and what is the minimum dropout voltage?
The ADP7183ACPZN3.3-R7 operates from an input voltage of -3.8 V to -5.5 V with a nominal dropout voltage of 0.13 V and a maximum dropout of 0.22 V. This low dropout allows the device to maintain regulation from a -4 V rail with less than 220 mV of headroom, enabling efficient negative LDO post-regulation directly from a -5 V charge pump in dual-supply analog designs.
What PSRR does the ADP7183ACPZN3.3-R7 achieve, and how does it help when post-regulating a switching converter output?
The ADP7183ACPZN3.3-R7 achieves greater than 70 dB of power supply rejection ratio at 1 kHz and maintains high PSRR up to 1 MHz, attenuating switching ripple from an inverting buck-boost or charge pump by more than 3000:1. This eliminates the need for a bulky LC output filter after the switching stage, reducing PCB area by approximately 50% in compact dual-supply precision instrumentation designs.
Is the ADP7183ACPZN3.3-R7 suitable for noise-sensitive RF receiver power supply designs, and what load current does it support?
Yes, the ADP7183ACPZN3.3-R7 is well-suited for RF LNA and mixer negative bias supplies requiring sub-10 µV RMS noise at -3.3 V. It supports load currents up to 200 mA continuous, which covers typical negative bias requirements for GaAs and GaN RF amplifier stages operating at 3.8 GHz and below where even modest power supply noise sidebands can degrade receiver noise figure by 1 dB to 3 dB.
