Pin Functions PIN I/O DESCRIPTION NAME DRV YZU Output pin. A 2.2- μF ceramic capacitor is connected from this pin to ground, for stability and to provide OUT 1 A3 O load transients. See Input and Output Capacitor Requirements. NC 2 — — No connection. Enable pin. A logic high signal on this pin turns the device on and regulates the voltage from IN to EN 3 C3 I OUT. A logic low on this pin turns off the device. Bias supply pin. TI recommends bypassing this input with a ceramic capacitor to ground for better BIAS 4 C1 I transient performance. See Input and Output Capacitor Requirements. GND 5 B2 — Ground pin. Input pin. This pin can be a maximum of 4.5 V; VIN must not exceed VBIAS. Bypass this input with a IN 6 A1 I ceramic capacitor to ground. See Input and Output Capacitor Requirements. 6 Specifications 6.1 Absolute Maximum Ratings At TJ = –40°C to 125°C (unless otherwise noted). All voltages are with respect to GND. (1) MIN MAX UNIT VIN (2) Input voltage (steady-state) –0.3 VBIAS or 5 (3) V VIN_PEAK (4) Peak transient input 5.5 V VBIAS Bias voltage –0.3 6 V VEN Enable voltage –0.3 6 V VOUT Output voltage –0.3 5 V IOUT Peak output current Internally limited Output short circuit duration Indefinite PDISS Total continuous power dissipation See Thermal Information TJ Operating junction temperature –55 125 °C Tstg Storage temperature –55 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) To ensure proper operation of the device it is necessary that VIN ≤ VBIAS under all conditions. (3) Whichever is less. (4) For durations no longer than 1ms each, for a total of no more than 1000 occurrences over the lifetime of the device.
