Se n s e General Description TS39150/1/2/3 are 1.5A ultra low dropout linear voltage regulators that provide low voltage, high current output fro m an ex tremely s mall package. These regulator offers extremely low dropout ( typically 400mV at 1.5A) and v ery low ground current (typically 12mA at 1.5A). TS39150/1/2/3 are fully protec ted against over current faults, reversed input polarity , reversed lead insertion, over temperature operation, positive and negative transient voltage spikes, logic level enable control and error flag which signals w henever the output falls out of regulation. On the TS39150/1/2/3, the enable pin may be tied to VIN if it is not required for enable control.

For guaranteed specifications and tes t conditions see the Electr ical Characteristics. Note 2: The device is not guaranteed to operate outside its oper ating rating. Note 3: Devices are ESD sensitive. Handling precautions recommended. Note 4: The maximum allowable pow er dissipation is a function of the maximum junction temperature, TJ, the junc tion to ambient ther mal resistance, ӨJA, and the ambient temperature, Ta. Exceeding the maximum allowable power dissipation w ill cause excessive die temperatur e, and the regulator will go into ther mal shutdown. The effec tive value of ӨJA can be r educed by using a heat sink, Pd(max) = (TJ(max) – Ta) / ӨJA. Note 5: Dropout voltage is defined as the input to output differential at w hich the output voltage drops -1% below its nominal v alue measured at 1V differential. Note 6: Ground pin current is the regulator quiescent c urrent. The total current drawn from the source is the sum of the ground pin current and output load current, IGND = IIN - IOUT for fix output voltage, , IGND = IIN - IOUT +10mA for fix reference output voltage in full load regulation. Note 7: VREF ≤ VOUT ≤ (VI N – 1V), 2.25V ≤ VIN ≤ 16V, 10mA ≤ IL ≤ 1.0A. Note 8: Output voltage temperature coefficient is ΔVOUT (worse cast) / (TJ(max) – TJ(MI N)) w here is TJ(max) +125 C and o TJ(MIN) is 0 C .

Its 630mV dropout voltage at full load and over temperature makes it especially valuable in battery power systems and as high efficiency noise filters in pos t regulator applications. U nlike nor mal N PN transistor design, wher e the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum dropout voltage, dropout perfor mance of the PN P output of these dev ices is limited only by low VCE saturation voltage. The TS3915x series is fully protec ted from damage due to fault conditions. Linear current limiting is provided. Output current during overload conditions is constant. Thermal shutdown the device when the die temperature exc eeds the maximum safe operating temperature. Transient protection allows dev ice survival even when the input voltage spikes above and below nominal. The output struc ture of these regulators allows voltages in excess of the desir ed output voltage to be applied without reverse current flow . Output Capacitor Requirement The TS3915x series requires an output capacitor to maintain stability and impr ove trans ient response is necessary. The value of this capacitor is dependent upon the output current, lower currents allow s maller capacitors. TS3915x series output capacitor selection is dependent upon the ESR of the output capacitor to maintain stability. When the output capacitor is 10uF or greater , the output capacitor should have an ESR less than 2Ω. This w ill improve transient response as well as promote stability. U ltra low ESR capacitors (
