1 HT73 XXLow Power Consumption LDOS election TablePart (for TO-92)73XX-A (for SOT-89) : XX stands for output lead free devices, TO-92 package will add a # mark at the end of the date code, whereas SOT-89package will add a # mark at the end of the 26, 2005 Features Ultra low quiescent current : 4mA (typ.) High input voltage (up to 12V) Output , , , , , , Output voltage accuracy: tolerance 3% Maximum output current : 250mA Low dropout voltage Low temperature coefficient TO-92, SOT-89 packageApplications Battery-powered equipment Voltage regulator for microprocessor Voltage regulator for LAN cards Wireless Communication equipment Audio/Video equipmentGeneral DescriptionThe HT73XX series is a set of three-terminal, low Power ,high voltage regulators implemented in CMOS technol-ogy. The series features extremely low quiescent cur-rent which is typically 4mA.

2 They allow input voltages ashigh as 12V. The device provides large current with asignificantly small dropout HT73XX consists of a high-precision voltage refer-ence, an error correction circuit, and a current limitedoutput driver. They are available with several fixed out-put voltages ranging from to CMOS technol-ogy ensures low dropout voltage and low currentconsumption. Although designed primarily as fixed volt-age regulators, these devices can be used with externalcomponents to generate variable voltages and DiagramPin AssignmentAbsolute Maximum RatingsSupply Voltage .. to VSS+14 VStorage Temperature ..-50 Cto125 CPower Consumption (*1) .. 500mWOperating Temperature ..-40 Cto85 CPower Consumption (*2) ..500mWNote: These are stress ratings only.
