EV2018-ZD-33-00A 16V, 500mA, Low Quiescent Current Line Regulator Evaluation Board DESCRIPTION FEATURES The EV2018-ZD-33-00A is an evaluation board 4.3V to 16V Input Range for the MP2018GZD-33, which is a low power 12A Quiescent Supply Current linear regulator that supplies power to systems Stable With Low-value Output Ceramic with high voltage batteries. It includes a wide Capacitor (> 0.47 F) 4.3V to 16V input range, low dropout voltage 500mA Specified Current and low quiescent supply current. The low Fixed Output Voltage quiescent current and low dropout voltage Output 2% Accuracy Over Temperature allows operations at extremely low power levels. Specified Current Limit Therefore, the MP2018GZD-33 is ideal for the Power Good low power microcontrollers and the battery- Programmable Power Good Delay powered equipments. Thermal Shutdown and Short-Circuit The EV2018-ZD-33-00A is a fully assembled Protection and tested evaluation board. It generates a -40C to +125C Specified Junction +3.3V output voltage at load current up to Temperature Range 500mA from 4.3V to 16V input range.

V (V) OUTEV2018-ZD-33-00A - 16V, 500mA, LOW QUIESCENT CURRENT LINEAR REGULATOR QUICK START GUIDDE 1. Connect the positive and negative terminals of the load to the VOUT and GND pins, respectively. Set load current between 0 500mA. Be aware that electronic loads represent a negative impedance to the regulator and if set to a too high current will trigger over-current- protection or short-current-protection. 2. Preset the power supply output between 4.3V and 16V, and then turn it off. If longer cables are used between the source and the EVB (>0.5m total), a damping capacitor should be installed at the input terminals. 3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins, respectively. 4. Turn the power supply on. The MP2018GZD-33 will automatically startup. The default VOUT is 3.3V. 5. Setting PGDL There is a delay time when PG asserts high, the delay time can be programmed by adding a capacitor on PGDL. To select a capacitor for PGDL, use below equation: t(ms) I ( A) PGDL PGDL C(nF) PGDL V(V) th PGDL The t is the desired delay time for PG asserts high, I is the PGDL charging current PGDL PGDL (5.5 A) and V is 1.65V. th PGDL EV2018-ZD-33-00A Rev. 1.1 www.MonolithicPower.com 2 3/12/2020 MPS Proprietary Information.
