TPS7A9401 Low Noise Linear Regulator 1A 0-5V Voltage Output Adjustable OCXO PLL Radar RF Microwave LDO Audio Power Supply

TPS7A9401 Ultra‑Low Noise Linear Power Supply Module – OCXO, RF & Microwave Power SupplyProduct Description:This module is based on the TPS7A9401ultra‑low noise linear regulator, specifically designed for RF and microwave applications such as phase‑locked loops (PLLs), radar systems, and OCXO (oven‑controlled crystal oscillator) power supplies. It delivers up to 1Aoutput current with an extremely low dropout voltage of 150mV at full load. The input voltage range is 1.7V to 5.7V, and the output is adjustable from 0V to 5.5V. The module offers excellent RMS noise performance (50dB @ 1MHz), making it ideal for noise‑sensitive circuits. Available with XH2.54‑2PIN input/output connectors or Type‑C input (5V only). Cables are not included.Specifications:Model: TPS7A9401Type: RF & Microwave LDO Regulator (PLL, Radar)Input Voltage Range: 1.7V – 5.7VOutput Voltage Range: 0V – 5.5V (adjustable)Max Output Current: 1000mA (1A)Minimum Dropout Voltage: 150mV @ 1ARMS Noise: 50dB @ 1MHzInput Connector: XH2.54‑2PIN or Type‑C (5V only for Type‑C) – cables not includedOutput Connector: XH2.54‑2PIN – cables not includedDimensions: 2.5 × 3.5 cmKey Features:Ultra‑low noise and high PSRR for critical RF/analog circuitsHigh output current capability (1A)Extremely low dropout voltage – ideal for low‑voltage systemsAdjustable output via potentiometer (or fixed resistors)Compact, easy‑to‑integrate designApplications:OCXO (oven‑controlled crystal oscillator) power supplyPLL / VCO / synthesizer power railsRadar and communication systemsHigh‑precision ADC / DAC referencesLaboratory and test equipmentPortable and battery‑powered RF devices
