5 V Low-Drop Voltage Regulator TLE 4266-2 Target Data Bipolar IC Features Output voltage tolerance 2 % 150 mA current capability Very low current consumption Low-drop voltage Overtemperature protection Reverse polarity proof Wide temperature range Suitable for use in automotive electronics Inhibit Type Ordering Code Package TLE 4266-2 G Q67006-A9485 TLE 4266-2 GS Q67006-A9486 New type SOT-223 P-SOT223-4-2 P-TSOP-8-1 P-TSOP-8-1 Functional Description The TLE 4266-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of <<1 A in OFF mode and 35 A in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted P-SOT223-4-2 and Micro-8 P-TSOP-8-1 package. In the PSOT223-4-2 housing it is pin compatible to the TLE 4266G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage VI in the range of 5.5 V < VI < 45 V is regulated to VQ = 5 V with an accuracy of 2%. The device operates in the temperature range of Tj = - 40 to 150 C. A High level at the INH pin switches the regulator on.

The regulation loop controls the output to achieve an output voltage of 5 V with an accuracy of 2% at an input voltage range of 5.5 V < VI < 45 V. For stability of the control loop the TLE 4266-2 output requires an output capacitor CQ of at least 10 F and an additional output resistor RQ . The resistor should be 1.5 when a 10 F capacitor is used and 1.0 for CQ 22F. The sum of RQ and the ESR of the capacitor must be kept below 5.5 . In order to achieve this the use of low-ESR tantalum or ceramic capacitors is recommended. The TLE 4266-2 can supply up to 150 mA. However for protection reasons at high input voltage above 25 V, the maximum output current is reduced (SOA protection). At the input of the regulator an input capacitor is necessary for compensating line influences. A resistor of approx. 1 in series with CI, can damp any oscillation occuring due the input inductivity and the input capacitor. The TLE 4266-2 includes the Inhibit function. For a voltage above 3.5 V at the INH pin the regulator is switched on.
