1 / 25 page November 2015 DocID028460 Rev 1 1/25 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. www.st.com LDK320 200 mA low quiescent current and high PSRR voltage regulator Datasheet - preliminary data Features Input voltage from 2.5 to 18 V Very low-dropout voltage (100 mV typ. @ 100 mA load) Low quiescent current (typ. 60 μA, 1 μA in off mode) High PSRR: 88 dB@120 Hz Low noise Output voltage tolerance: ± 2.0% @ 25 °C; (±0.5% version available on request) 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 COUT = 1 μF 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 Industrial 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 l ower than 1 μA. This device also includes a short-circuit current limiting, thermal and SOA protections. SOT23-5 L SOT-8 9 |
