LD39100 Datasheet | STMicroelectronics

LD39100 Automotive grade 1 A, low quiescent current, low-noise voltage regulator DFN6 (3x3 mm) Maturity status link LD39100 Features - AEC-Q100 qualified - Input voltage from 1.5 to 5.5 V - Ultra-low dropout voltage (200 mV typ. at 1 A load) - Very low quiescent current (20 µA typ. at no load, 200 µA typ. at 1 A load, 1 µA max. in off mode) - Very low-noise with no bypass capacitor (30 µ VRMS at VOUT = 0.8 V) - Output voltage tolerance: ±2.0% at 25 °C - 1 A guaranteed output current - Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step and adjustable from 0.8 - Logic-controlled electronic shutdown - Stable with ceramic capacitors COUT = 1 µF - Internal current and thermal limit - DFN6 (3x3 mm) package - Temperature range: -40 °C to 125 °C Applications - Printers - Game consoles - puter - Consumer applications - Automotive post regulation Description The LD39100 provides 1 A maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV. The device is stable with ceramic capacitors on the input and output. The ultra-low dropout voltage, low quiescent current and low-noise Features make it suitable for low power battery-powered applications. Power supply rejection is 70 dB at low frequency and starts to roll off at 10 kHz. Enable logic control function puts the LD39100 in shutdown mode, allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection. LD39100 is available also in AEC-Q100 qualified version, in the DFN6 (3x3 mm) with wettable flank package.
