TLE9261-3QX
External Voltage Regulator 3
Note: At T_j > 125°C, the power transistor leakage could be increased, which has to be added to the quiescent
current of the application independently if the regulator is turned on/off. To prevent an over-voltage condition
at no load due to this increased leakage, an internal clamping structure will automatically turn on at typ.
200mV above the upper limit of the programmed output voltage.
Note: There is no thermal protection available for the external PNP transistor. Therefore, the application must be
designed to avoid overheating of the PNP via the shunt current limitation in stand alone configuration and
by selecting the proper ICC1/ICC3 ratio in load-sharing configuration.
Note: In SBC Stop Mode, the same output voltage tolerance applies as in SBC Normal Mode when I_VCC3 has
exceeded the selected active peak threshold (I_{VCC3base,Ipeak}) but with increased current consumption.
