LD2980CM50TR ST Voltage Regulators - Linear

The LD2980CM50TR is a low-noise, ultra-low dropout voltage regulator from STMicroelectronics in SOT-23-5 package, providing fixed 5V output with up to 50 mA current capability . For selection, verify input voltage up to 16V, typical dropout voltage of 120 mV at 50 mA load (7 mV at 1 mA), quiescent current of 80 µA typical (1 µA max in shutdown), PSRR of 63 dB at 1 kHz , output tolerance of ±1.8% (3.24V to 3.36V for 3.3V version), and operating temperature from -40°C to +125°C. Features include logic-controlled electronic shutdown via inhibit pin (TTL compatible), stability with low-ESR ceramic capacitors, internal current limiting, and thermal protection . Ideal for instrumentation, switch-mode power supply post-regulation, audio systems, industrial control boards, battery-powered portable equipment, and any application requiring low-noise 5V regulation with ultra-low dropout and shutdown capability for standby mode power management .
