Functional Block Diagram DRV PACKAGE 2mm × 2mm SON (TOP VIEW) Table 1. PIN DESCRIPTIONS TPS718xx, TPS719xx NAME NO. DESCRIPTION OUT1 1 Output of Regulator 1. A small ceramic capacitor (typically ≥ 1µF) is needed from this pin to ground to assure stability. IN 2 Input supply to both regulators. OUT2 3 Output of Regulator 2. A small ceramic capacitor (typically ≥ 1µF) is needed from this pin to ground to assure stability. Enable pin for Regulator 2. Driving the Enable pin (EN2) high turns on Regulator 2. Driving this pin low puts Regulator 2 EN2 4 into shutdown mode, reducing operating current. GND 5 Ground. Thermal pad should also be connected to ground. Enable pin for Regulator 1. Driving the Enable pin (EN1) high turns on Regulator 1. Driving this pin low puts Regulator 1 EN1 6 into shutdown mode, reducing operating current. 4 Submit Documentation Feedback |
