With output voltage range from 1.25 V to 5 V the first regulator can source 150 mA and the second regulator can source 300 mA. The open drain driver has the capability to drive LED's for backlighting applications. VIN VIN is the input supply pin for both LDO's. The bypass capacitor for this pin is not critical as long as the input supply has low enough source impedance. For practical circuits, a 1.0 F or larger ceramic capacitor is recommended. When the source impedance is not low enough and/or the source is several inches from the SiP2211, then a larger input bypass capacitor is needed. When the source impedance, wire and trace impedance are unknown, it is recommended that an input bypass capacitor be used of a value that is equal to or greater than the output capacitor. VOUT1,2 (LDO Outputs) The VOUT is the output voltage of the regulator. Connect a bypass capacitor from VOUTx to ground. The output capacitor can be any value from 1.0 F to 10.0 F. A ceramic capacitor with X5R or X7R dielectric type is recommended for best output noise, line transient, and load transient performance. Enable The EN1 and EN2 pins control the turning on and off of their respective regulators in the SiP2211. VOUT of both outputs are guaranteed to be on when the Enable pin voltage is equal or greater than 1.8 V. VOUT is guaranteed to be off when the Enable pin voltage equals or is less than 0.6 V. To automatically turn on VOUT whenever the Input is applied, tie the Enable pin to VIN. Bypass Capacitor For low noise application and/or increase in power supply rejection ration (PSRR) connect a high frequency ceramic capacitor from BP to ground. A 0.01 F X5R or X7R ceramic capacitor is recommended. Vishay Siliconix maintains worldwide manufacturing capability. Products may be manufactured at one of several qualified locations.
