Le blog de l'entreprise Mingjiada Supplies ADI ADP1764 4A Low-Voltage Input Ultra-Low-Noise LDO Linear Regulator

Shenzhen Mingjiada Electronics Co., Ltd. is an authorized stockist of ADI (Analog Devices) products, specializing in the full range of ADI power management ICs. We carry the ADP1764 in stock—all genuine, factory-direct products with stable inventory—and support both small-batch sample orders and large-volume orders. Please feel free to contact us for inquiries and quotes.

The ADP1764 is a 4A, low-input-voltage, ultra-low-noise CMOS low-dropout linear regulator (LDO) introduced by ADI. It is specifically designed for precision power supplies in low-core-voltage FPGAs, high-speed ADCs, RF signal chains, servers, and AI boards. It operates on a single power supply, requiring no additional external bias power supply. It features a low dropout voltage and excellent noise performance, and can operate stably with a small-capacity ceramic capacitor, significantly simplifying PCB layout. It is the preferred solution for high-performance, low-noise power rails.

ADP1764 Product Features

1. Maximum output current: 4A

2. Input voltage range: 1.10V to 1.98V; no external bias power supply required

3. Fixed output voltage: 0.55 V to 1.5 V; adjustable output voltage: 0.5 V to 1.5 V

4. Ultra-low noise: 2 µV rms (100 Hz to 100 kHz), noise spectral density of 5 nV/√Hz

5. Low dropout voltage: Typical dropout voltage of 47 mV at a 4 A load, stable regulation even with a small margin

6. High power supply rejection ratio (PSRR), excellent linearity, and load transient response

7. Requires only a 22 µF ceramic output capacitor for stable operation, saving PCB space

8. Built-in PG (Power Good) indicator pin (open-drain output), soft-start, current-limit protection, and thermal shutdown protection

9. CMOS architecture, suitable for low-voltage, high-current precision power supply applications
