The device features ultra low ground current and dropout voltage to prolong battery life in portable electronics. The Si9185 offers line/load transient response and ripple rejection superior to that of bipolar or BiCMOS LDO regulators, and is designed to drive lower cost ceramic, as well as tantalum, output capacitors. An external noise bypass capacitor connected to the device’s CNOISE pin will lower the LDO’s output noise for low noise applications. The Si9185 also includes an out-of-regulation error flag. If a capacitor is connected to the device’s delay pin, the error flag output pin will generate a delayed power-on-reset signal. The device is guaranteed stable from maximum load current down to 0-mA load. The Si9185 is available in a MLP33 PowerPAK package. This allows enhanced heat transfer to the PC board. The Si9185 is specified to operate over the industrial temperature range of –40 _C to +85_C. TYPICAL APPLICATIONS CIRCUITS FIGURE 1. Fixed Output FIGURE 2. Adjustable Output FIGURE 3.
