LP3996QSDX-1833/NOPB

LP3996-Q1 www.ti.com SNVSA17 – OCTOBER 2013 Dual Linear Regulator with 300 mA and 150 mA Outputs and Power-On-Reset Check for Samples: LP3996-Q1 FEATURES DESCRIPTION • • The LP3996-Q1 is a dual low dropout regulator with power-on-reset circuit. The first regulator can source 150 mA, while the second is capable of sourcing 300 mA and has a power-on-reset function included. 1 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 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 comes in a 10-pin, 3 mm x 3 mm package.
