HMC1060LP3E v00.1211 QUAD LOW NOISE HIGH PSRRLINEAR VOLTAGE REGULATORPin Descriptions Pin number Function description interface Schematic 1 Vdd Unregulated power supply input t 2 gnd Supply ground M enable input, ttL Logic Level. the Vrx outputs are g - S 3 en floating (high impedance) when en = Low. in n io it d reference voltage (band-gap) output. Cannot be used to source/sink current to/from external circuits. Voltage on n reF pin = 1.17 at +27°C when PtAt Mode is disabled, 4 reF o and equals 1.37 V at +27°C when PtAt Mode is enabled. Must be measured with 10 gΩ meter such as Agilent 33410A, typical 10 MΩ dVM may read erroneously. r C e w 5 HV3 Used with rd3 to set Vr3 output voltage. o P 13 HV2 Used with rd2 to set Vr2 output voltage. 16 HV1 Used with rd1 to set Vr1 output voltage. Sets all output voltages in PtAt mode when connected to 8 PtAtB gnd, default mode when open 6 rd3 Feedback for Vr3. 7 rd4 Feedback for Vr4 14 rd2 Feedback for Vr2 15 rd1 Feedback for Vr1 Inf F or o m r p atio r n ifc ur e n , d ishe e d lbiv y e A r n y a alog n D d t evic o p es is la beclie o eved rd to ebre sa: H ccur iattti e tae M nd re ilicarbloew .
