TS29152 1.5A Ultra Low Dropout Voltage Regulator TO-220-5L Pin Definition: 1. Enable 2. Input 3. Ground 4. Output 5. Adjust General Description TS29152 is using process with a PNP pass element for high current, high accuracy and low dropout voltage regulators. These regulator s feature 350mV(typ) dropout voltages and very low ground current, these devices also find applications in lower current and low dropout critical systems, where their tiny dropout voltage and ground current values are important attributes. TS29152 isfully protected 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 whenever the output falls out of regulation. On the TS29152, the enable pin may be tied to VIN if it is not required for enable control.

For guaranteed specifications and test conditions see the Electrical Characteristics. Note 2: Maximum positive supply voltage of 60V must be limited duration (<100mS) and duty cycle (<1%). Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ, the junction to ambient thermal resistance, θ, and the ambient temperature , Ta. Exceeding the maximum allowable power dissipation will...

TS29152 1.5A Ultra Low Dropout Voltage Regulator Typical Application Circuit The TS29152 is high performance with low dropout voltage regulator suitable for moderate to high current and voltage regulator application. Its 350mA(typ) dropout voltage at full load and over temperature makes it especially valuable in battery power systems and as high efficiency noise filters in post regulator applications. Unlike normal NPN transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum dropout voltage, dropout performance of the PNP output of...

TS29152 1.5A Ultra Low Dropout Voltage Regulator Thermal Characteristics (Continue) The next parameter which must be calculated is the maximum allowable temperature rise, TR(max). this is calculated by the using to formula: TR(max) = TJ(max) – TA(max) o Where: TJ(max) is the maximum allowable junction temperature, which is 125 C for commercial grade parts. TA(max) is the maximum ambient temperature which will be encountered in the application. Using the calculated values for TR(max) and PD, the maximum allowable value for the junction to ambient thermal resistance, θJA, can now be found: θJA...
