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. 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. VIN The POR is an open drain output that goes low when VOUT2 is less than 5 % of its nominal value. As with any open drain output, an external pull up resistor is needed. The POR pin is disconnected if not used. 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 SiP2214, 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 Enable pin controls the turning on and off of both regulators of the SiP2214. 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 For the adjustable voltage version of the SiP2214, LDO1 and LDO2, have separate and independent Enable control pins. Power-On Reset (POR) SET When a capacitor is connected from SET to GROUND, the POR signal transition from low to high is delayed. This delayed POR signal can be used as the power-on reset signal for the application system. To set the POR delay time refer to the POR Delay curve to determine the capacitor value. The Set pin should be an open circuit if not used. OPEN-Drain Driver (DRV) The SW pin a logic level input put that controls the DRV pin. The switch pin is an active high input and should not be left floating. The drive pin is an open drain output able to sink 150 mA of current. 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.
