... Soft-start reduces inrush current. Other features include a logic-controlled shutdown mode, short-circuit protection, and thermal-overload protection. The MAX8517 features a power-OK (POK) output that transitions high when the regulator output is within ±10% of its nominal output voltage. The MAX8518 features a 150ms power-on reset output. ...

... Regulator Output. Bypass with a 4.7µF ceramic capacitor to GND (a smaller OUT capacitor can be used if maximum load is less than 1A, i.e., C (max) x (1µF/200mA). Power-OK Output (MAX8517 Only). Open-drain output. Connect to a positive POK supply with a pullup resistor. If not used, leave pin unconnected. See the Detailed Description. ...
