LDK320AM-R ST Linear

The LDK320AM-R from STMicroelectronics is an adjustable low-dropout linear regulator that delivers up to 200 mA from a wide 2.5 V–18 V input. For selection, key specifications include a 100 mV typical dropout at 100 mA, a 60 μA quiescent current (1 μA in off mode through the EN logic), an 88 dB PSRR at 120 Hz, and ±0.5 % output accuracy at 25 °C (A version), with a 1.2 V–12 V adjustable range and a ‑40 °C to +125 °C operating junction temperature. The device is stable with a 1 μF ceramic capacitor and includes current limiting, SOA, and thermal protections. In application, it powers microcontrollers, sensors, and analog front‑ends in digital cameras, TVs, BD/DVD players, PCs, industrial automation, and portable battery‑powered devices where a compact SOT‑23‑5 footprint, low standby drain, and high PSRR are critical.
