Product Overview
LDQ40PU50RY is a high accuracy voltage regulator, which provides 250mA of current. This device is stabilized with a small ceramic capacitor on the output. The low drop, low quiescent current, and short-circuit protection make the LDQ40 suitable for low power battery-operated applications. An enable logic control function puts the LDQ40 in shutdown mode allowing a total current consumption lower than 0.3µA. Thermal protection is also included. Applications include EV powertrain, always-on battery connected application, infotainment and instrument clusters, ADAS.
- Input voltage from 3.3V to 40V, logic-controlled electronic shutdown
- Internal current limit, short-circuit protection
- Standby current is 0.3µA typical at (VIN = 14V)
- Quiescent current during regulation is 2µA typical at (VIN from 2.5V to 40V no load)
- Output current limit is 500mA typical at (VOUT = 90% VOUT(NOM))
- Dropout voltage is 500mV typical at (IOUT = 250mA)
- Static load regulation is 2mV typical at (IOUT = 1mA to 250mA)
- Output voltage accuracy is +1.5% typical at (IOUT = 1mA to 250mA), 5V VOUT voltage
- Operating junction temperature range from -40°C to 150°C, DFN6 package
