Additional Infomation About Product

LDK320 200 mA high accuracy and high PSRR voltage regulator Features Input voltage from 2.5 to 18 V Very low-dropout voltage (100 mV typ. 100 mA load) SOT23-5L SOT-89 Low quiescent current (typ. 60 A, 1 A in off mode) High PSRR: 88 dB 120 Hz Low noise Output voltage tolerance: 0.5% 25 C (LDK320A) or 2% 25 C Output current up to 200 mA Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable Logic-controlled electronic shutdown Compatible with ceramic capacitor C = 1 F OUT Current, SOA and thermal protections Available in SOT23-5L and SOT-89 packages Temperature range: -40 C to 125 C Applications DSC TV BD, DVD PC Maturity status link Industrial LDK320 Description The LDK320 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 18 V, with a typical dropout voltage of 100 mV. It is stabilized with a ceramic capacitor on the output. The very good dynamic characteristic, combined with low drop voltage and low quiescent current make it suitable for low power battery-powered applications. The enable logic control function allows the LDK320 to be in shutdown mode by consuming a total current lower than 1 A. This device also includes a short-circuit current limiting, thermal and SOA protections.
