SC4213HSTRT Semtech

SC4213H Very Low Input /Very Low Dropout 0.5 Amp Regulator With Enable POWER MANAGEMENT Features Description Input Voltage as low as 1.4V The SC4213H is a high performance positive voltage regu- 75mV dropout 0.5A lator designed for use in applications requiring very low Adjustable output from 0.5V input voltage and very low dropout voltage at up to 0.5 Over current and over temperature protection amperes. It operates with a Vin as low as 1.4V. The SC4213H Enable pin features ultra low dropout, ideal for applications where 10A quiescent current in shutdown Vout is very close to Vin. Additionally, the SC4213H has an Full industrial temperature range enable pin to further reduce power dissipation while shut- Fully WEEE and Halogen free. RoHS compliant down. The SC4213H provides excellent regulation over variations in line, load and temperature. Applications The SC4213H is available in an SOIC-8 package. The output voltage can be set via an external divider as shown in the Telecom/Networking cards typical application circuit.
