1 / 8 page Ordering number : ENN7596 52804TN (OT) No. 7596-1/8 Overview The LA5657H provides 10 V/2.2 A and 5 V/1.4 A external pnp transistor based low-saturation regulators with standby functions, as well as 3.3 V, 5 V, and 8 V constant voltage, open collector, and VCC linked (VCC - 1 V) outputs that can be controlled from serial data (CCB). It also includes three reset detection circuits for the VDD, ACC, and battery systems. The LA5657H is an optimal power supply IC for car audio systems and similar products. Features • Built-in 10 V and 5 V regulators (external pnp transistor required) with standby (on/off) functions • Extensive set of output systems: two 8 V systems, single 5 V, 3.25 V, and 5 to 9.7 V (set with an external resistor) systems, four open-collector output systems, and two VCC linked systems. • Three reset circuits: ACC, VDD (with delay circuit), and BATT • Full complement of protection circuits — Overcurrent protection circuits for all output systems except the open collector and reset circuits — Thermal protection circuits for all outputs except the reset circuits Package Dimensions unit: mm 3233A-HSOP28H (6.2) 28 15 114 0.8 15.2 2.7 0.3 0.25 (0.8) 2.0 SANYO: HSOP28H (375 mil) [LA5657H] LA5657H SANYO Electric Co.,Ltd.
