In the SiP2213, the outputs are sequenced at power on. The output of LDO #1 has to settle before the output of LDO #2 begins turning on. In addition to the LDOs, an open drain output has been included, which is capable of sinking 150 mA. The SiP2213 offers a low dropout, low ground current and extremely low noise with the addition of a bypass capacitor. Protection features include POR with adjustable delay, undervoltage lockout, output current limit, and thermal shutdown. The fixed output version of SiP2213 is available in the MLP33-10 PowerPAK package and the adjustable version is available in the MLP44-16 PowerPAK package. Both packages are specified to operate over the range of –40_C to 85_C.

C, 09-May-05 SiP2213 New Product Vishay Siliconix DETAILED OPERATION The SiP2213 is a low drop out, low quiescent current monolithic dual linear regulator, with power-on reset and open drain driver output features. 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 regulators are sequentially turned on with the 150 mA regulator turned on first and then the 300-mA regulator. 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 mF or larger ceramic capacitor is recommended. When the source impedance is not low enough and/or the source is several inches from the SiP2213, 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) with the 150 mA regulator turned on first and then the 300mA regulator. 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. Power-On Reset (POR) 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. 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 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 mF to 10.0 mF. A ceramic capacitor with X5R or X7R dielectric type is recommended for best output noise, line transient, and load transient performance. 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. Enable Bypass Capacitor The Enable pin controls the turning on and off of both regulators of the SiP2213. VOUT of both outputs are guaranteed to be on when the Enable pin voltage is equal or greater than 1.8 V; the regulators are sequentially turned on 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-mF X5R or X7R ceramic capacitor is recommended. Vishay Siliconix maintains worldwide manufacturing capability. Products may be manufactured at one of several qualified locations.
