The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

D1 www.fairchildsemi.com 7 The FDZ1040L is a low-RDS(ON) P-channel load switch packaged in space-saving 0.8x0.8 WLCSP. of 1-4 V. The ON pin, an active HIGH TTL-compatible input that supports input as low as 0.7 V, controls the state of the switch. The core of the device is a 80 mΩ P-channel MOSFET capable of functioning over a wide input operating range Applications Information VIN VIN = 1 -4 V CIN VOUT ON OFF ON GND Figure 21. COUT RL Typical Application Input Capacitor Output Capacitor To reduce device inrush current effect, a 0.1 µF ceramic capacitor, CIN, is recommended close to the VIN pin. A higher value of CIN can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load. FDZ1040L works without an output capacitor. However, if parasitic board inductance forces VOUT below GND when switching off, a 0.1 µF capacitor, COUT, should be placed between the VOUT and GND pins. © 2010 Fairchild Semiconductor Corporation FDZ1040L • Rev.
