SIEMENS70325 Datasheet
SIEMENS70325 Price The shutdown feature can be used to preventcharge pump switching during noise sensitive intervals. Since the charge pump oscillatoris disabled during shutdown,output switch- ing noise can be eliminated while the external pull-down is active. The LTC1502-3.3 takes between 200cs and 500cs to switch from shutdown to active mode once the pull-down device has been turned off (assuming a lOOpF external capacitance to GND on the Cl-/S HDN pin). AlOOk pull-up resistorfrom VIN to Cl-/S HDN will speed up thistransition by a factor of five at the expense of 10aA orso of additional shutdown current. To maintain regulation, a sufficiently large output capacitor must be used to prevent excessive VOUT droop while the charge pump is in shutdown. Also, there must be adequate time for the charge pump to recharge the output capacitor while the part is active. In other words,the average load current must be low enough for the LTC1502-3.3 to maintain a 3.3V output while the part is active. SIEMENS70325 on stock
