HA17723 Datasheet | Hitachi Semiconductor

Description The HA17723 high-accuracy general-purpose voltage regulator features a very low stand-by current, (quiescent current) a low temperature drift, and high ripple rejection ratio. If you need over than 150m A output current, adding external PNP or NPN transistor. This voltage regulator is suitable for various applications, for example, series or parallel regulator, switching regulator.

Above 25°C derate by 8.3m W/°C 2. Allowable temperature of IC junction part, Tj (max), is as shown below. Tj (max) = θj - a - Pc (max)+Ta (θ j - a is thermal resistance value during mounting, and Pc (max) is the maximum value of IC power dissipation.) Therefore, to keep Tj (max) ≤ 125°C, wiring density and board material must be selected according to the board thermal conductivity ratio shown below. Be careful that the value of Pc (max) does not exceed that PT.
