General Description
TS29150/1/2/3 are 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. TS29150/1/2/3 series are fully 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 TS29151 and TS29152, the enable pin may be tied to VIN if it is not required for enable control.

Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. 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 cause excessive die temperature, and the regulator will go into thermal shutdown. The
effective value of θJA can be reduced by using a heatsink.
Note 4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of
the ground pin current and output load current.
Note 6: Output current will decrease with increasing temperature, but it will be not dropped below 1.5A at the
maximum specified temperature.
Note 7: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation
is applied, excluding load or line regulation effects. Specification are for a 200mA load pulse at VIN =20V(a
4W pulse) for T=10mS
Note 8: Comparator thresholds are expressed in terms of a voltage differential at the adjust terminal below the
nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage
change, multiply by the error amplifier gain = VOUT/VREF = (R1+R2) / R2. For example, at a programmed
output voltage of 5V, the error output is guaranteed to go low when the output drops by 95mV x 5V / 1.24V =
384mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout warning
occurring at typically 5% below nominal, 7.7% guaranteed.

1.5A Ultra Low Dropout Voltage Regulator
with Multi-Function
Typical Application Circuit
The TS29150/1/2/3 series are 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 these devices is limited only by low VCE
saturation voltage.
The TS29150/1/2/3 series is fully protected 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
exceeds the maximum safe operating temperature. Transient protection allows device survival even when the input
voltage spikes above and below nominal. The output structure of these regulators allows voltages in excess of the
desired output voltage to be applied without reverse current flow.
Capacitor Requirement
The TS29150/1/2/3 series requires an output capacitor to maintain stability and improve transient response is
necessary. The value of this capacitor is dependent upon the output current, lower currents allow smaller capacitors.
TS29150/1/2/3 series regulators are stable with the 10uF minimum capacitor value at full load. Where the regulator
is powered from a source with high AC impedance, a 0.1uF capacitor connected between input and ground is
recommended. The capacitor should have good characteristics to above 250KHz. The capacitance values will be
help to improved transient response, ripple rejection and output noise.
Minimum Load Current
The TS29150/1/2/3 series is specified between finite loads. If the output current is too small leakage currents
dominate and the output voltage rises. A 10mA minimum load current swamps any expected leakage current across
the operating temperature range.
Thermal Characteristics
TS29150/1/2/3 series linear regulators are simple to use, the most complicated design parameters to consider are
thermal characteristics, thermal design requires the following application specification parameters:
* Maximum ambient temperature, Ta
* Output current, IOUT
* Output voltage, VOUT
* Input voltage, VIN
We calculate the power dissipation of the regulator from these numbers and the device parameters from this data
sheet. A heatsink may be required depending on the maximum power dissipation and maximum ambient
temperature of the application. Under all possible operating conditions, the junction temperature must be within the
range specified under absolute maximum ratings. To determine if the heatsink is required, the power dissipated by
the regulator, PD must be calculated.
The below formula shows the voltages and currents for calculating the PD in the regulator:
IIN = IL / IG
PD = (VIN - VOUT) * IL + (VIN) * IG
Ex. PD = (3.3V-2.5V) * 0.5A + 3.3V * 11mA
= 400mW + 36mW
= 436mW
Remark: IL is output load current,
IG is ground current.
VIN is input voltage
VOUT is output voltage

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)
Where: TJ(max) is the maximum allowable junction temperature, which is 125oC 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 = TR(max) / PD
Adjustable Regulator Design
The adjustable regulator versions (TS29152/53) is allow to programming the output voltage anywhere between 1.25
and the 26V maximum operating rating of the family. Two resistors are used. Resistors can be quite large up to 1MΩ,
because of the very high input impedance and low bias current of the sense comparator, the resistor values are
calculated by:
R1 = R2 * [(VOUT / 1.24) – 1]
Where is Vout the desired output voltage. Above application circuit shows component definition. Applications with
widely varying load currents may scale the resistors to draw the minimum load current required for proper operation.
Error Flag
TS29151 and TS29153 versions feature an Error Flag, which looks at the output voltage and signals an error
condition when this voltage drops 5% below its expected value. The error flag is an open-collector output that pulls
low under fault conditions. It may sink 10mA. Low output voltage signifies a number of possible problems, including
an over-current fault (the device is in current limit) and low input voltage. The flag output is inoperative during over
temperature shutdown conditions.
Enable Input
TS29151 and TS29152 versions feature an enable (EN) input that allows ON/OFF control of the device. Special
design allows “zero” current drain when the device is disabled–only microamperes of leakage current flow. The EN
input has TTL/CMOS compatible thresholds for simple interfacing with logic, or may be directly tied to ≤30V.
Enabling the regulator requires approximately 20uA of current.
