FEATURES - 2 2 LDO Outputs with Independent Enable - 1.5% Accuracy at Room Temperature, 3% Over Temperature - Power-On-Reset Function with Adjustable Delay - Thermal Shutdown Protection - Stable with Ceramic Capacitors - Qualified for Automotive Applications - AEC-Q100 Test Guidance with the Following Results: - Device Temperature Grade 1: - 40°C to 125°C - Device HBM ESD Classification Level H2 - Device CDM ESD Classification Level C4B APPLICATIONS - Cellular Handsets - PDAs - Wireless Network Adaptors - Automotive DESCRIPTION The LP3996-Q1 is a dual low dropout regulator with power-on-reset circuit. The first regulator can source 150 m A, while the second is capable of sourcing 300 m A and has a power-on-reset function included. The LP3996-Q1 provides 1.5% accuracy requiring an ultra low quiescent current of 35 µA. Separate enable pins allow each output of the LP3996-Q1 to be shut down, drawing virtually zero current. The device is designed to be stable with small footprint ceramic capacitors down to 1 µF. An external capacitor may be used to set the POR delay time as required. The LP3996-Q1 is available in fixed output voltages and es in a 10-pin, 3 mm x 3 mm package.
