PRODUCTION DATA. LP5907 SNVS798L – APRIL 2012 – REVISED SEPTEMBER 2016 LP5907 250-mA Ultra-Low-Noise, Low-IQ LDO 1 1 Features 1 • Input Voltage Range: 2.2 V to 5.5 V • Output Voltage Range: 1.2 V to 4.5 V • Output Current: 250 mA • Stable with 1-µF Ceramic Input and Output Capacitors • No Noise Bypass Capacitor Required • Remote Output Capacitor Placement • Thermal-Overload and Short-Circuit Protection • –40°C to 125°C Junction Temperature Range for Operation • Low Output Voltage Noise: < 6.5 µVRMS • PSRR: 82 dB at 1 kHz • Output Voltage Tolerance: ±2% • Virtually Zero IQ (Disabled): < 1 µA • Very Low IQ (Enabled): 12 µA • Start-up Time: 80 µs • Low Dropout: 120 mV (typical) 2 Applications • Mobile Phones, Tablets • Digital Cameras and Audio Devices • Portable and Battery-Powered Equipment • Portable Medical Equipment • Smart Meters • RF, PLL, VCO, and Clock Power Supplies • IP Cameras • Drones • Field Transmitters 3 Description The LP5907 is a low-noise LDO that can supply up to 250 mA output current. Designed to meet the requirements of RF and analog circuits, the LP5907 device provides low noise, high PSRR, low quiescent current, and low line or load transient response figures. Using new innovative design techniques, the LP5907 offers class-leading noise performance without a noise bypass capacitor and the ability for remote output capacitor placement. The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (no separate noise bypass capacitor is required). This device is available with fixed output voltages from 1.2 V to 4.5 V in 25-mV steps. Contact Texas Instruments Sales for specific voltage option needs.
