R070LD10L-XX-TN4-R

UNISONIC TECHNOLOGIES CO., LTD R070LD10 VOLTAGE REGULATOR DESCRIPTION As the UTC linear integrated LDO, the UTC R070LD10 shows a high current, high accuracy, low-dropout voltage which built in on/off function. The features are: low dropout voltage, very low ground current. Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes). LINEAR INTEGRATED CIRCUIT FEATURES * Built-in ON/OFF Function * Over Current Protection Function * Over Heat Protection Function * Adjustable DC Output Voltage ORDERING INFORMATION Ordering Number Lead Free Halogen Free R070LD10L-xx-TN4-R R070LD10G-xx-TN4-R Note: xx: Output Voltage, refer to Marking Information.
