To disable the device, connect to Ground. If this function is not in use, connect to Vin. 2 Vin Positive Power Supply Input Voltage 3 Ground Power Supply Ground 4 Vout Regulated Output Voltage 5 Adj (Adjustable Version) This pin is connected to the resistor divider network and programs the output voltage. 5 Error Flag (Fixed Version) An Error Flag is triggered when the output voltage is out of regulation excluding transient signals that may occur. Requires a pullup resistor f 100 kW. MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage Vin 18 V Output Pin Voltage Vout −0.3 to Vin +0.3 V Adjust Pin Voltage Vadj −0.3 to Vin +0.3 V Enable Pin Voltage Ven −0.3 to Vin +0.3 V Error Flag Voltage Vef −0.3 to Vin +0.3 V Error Flag Current Ief 3.0 mA Thermal Characteristics Thermal Resistance, Junction−to−Air Thermal Resistance, Junction−to−Case RθJA RθJC 100 8.0 °C/W Operating Junction Temperature Range TJ −40 to +150 °C Storage Temperature Range Tstg −55 to +150 °C Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. NOTE: This device series contains ESD protection and exceeds the following tests: Human Body Model (HBM) JESD 22−A114−B Machine Model (MM) JESD 22−A115−A. The maximum package power dissipation is: P D + T J(max) * T A RqJA The bipolar process employed for this IC is fully characterized and rated for reliable 18 V VCCmax operation. To avoid damaging the part or degrading it’s reliability, power dissipation transients should be limited to under 20 W for DPAK. For open−circuit to short−circuit transient, PDTransient = VCCmax * ISC. |
