TC57 Series
Linear Regulator Controller
FEATURES
GENERAL DESCRIPTION
■ Low Dropout Voltage:
The TC57 is a low dropout regulator controller that
operates with an external PNP pass transistor, allowing the
user to tailor the LDO characteristics to suit the application
at hand. This results in lower dropout operation (and often
lower cost) compared with traditional linear regulators with
on-board pass transistors. The maximum output current of
a TC57-based regulator circuit is limited only by the charac-
teristics of the external pass transistor. For example, a
maximum output current of 650 mA (with a dropout voltage
of 100 mV) results when an FZT749 pass transistor is used,
while a Darlington configuration can deliver up to 4A.
Flexibility, andsuperiorperformancemakethisfamilyof
regulator controllers the ideal choice in applications where
low dropout voltage and low installed cost are key.

NOTES: 1. VR is the regulator output voltage setting.
2. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured
at a 1V differential.
3. Varies with type of pass transistor used. Numbers shown are for the test circuit of Figure 1.
4. The product of IEXT x VEXT must be less than the maximum allowable power dissipation.

Linear Regulator Controller
TC57 Series
For example, assume a desired continuous output cur-
rent of 1.0A, an input voltage of 5V, and an FZT749 pass
transistor. The FZT749 has a typical hFE of 170, and a VBE
of 0.8V; both specified at a collector current of 1.0A. Substi-
tuting these values into the equation above results in an RB
value of 704Ω (closest standard value = 680Ω).
DETAILED DESCRIPTION
The TC57 series of precision low dropout regulator
controllers use an external PNP transistor to accommodate
a wide range of output currents. A series resistor (RB) limits
the maximum base current drawn from the PNP transistor.
Limiting the base drive both determines the regulator’s
output current capability, as well as limits ground current
whenthedeviceisoperatedindropout.ThePNPtransistor’s
VCE(SAT) is the only factor limiting dropout voltage.
Pull-Up Resistor and Output Capacitor (Figure 2)
A pull-up resistor (RBE, installed between the base and
emitter of the pass transistor) facilitates rapid turn-off of the
pass transistor in the event of a sudden decrease in load.
Recommended values for this resistor are between 20 KΩ
and 47 KΩ. A Tantalum output capacitor of at least 10 µF
mustbeusedtoguaranteestability. Highervaluesdecrease
output noise and eliminate power-on overshoot, but extend
power-up times. Table 2a lists several capacitor choices.
Transistor Selection
The PNP pass transistor must have satisfactory power
dissipation,currentgain,andcollectorcurrentspecifications
to suit the application at hand. The maximum output current
the circuit can deliver is influenced by hFE. The highest
guaranteed output current is given by:
Input Capacitor (Figure 2)
ILOAD(MAX) = 25 mA x hFE(MIN)
Theadditionofaninputcapacitorfurtherreducesoutput
noise, and negates the effects of power supply input imped-
ance. A 10 µF(min) Tantalum capacitor is recommended.
Equation 1.
Thetransistor’sactualpowerdissipation(PD)isequalto
the maximum load current times the maximum input/output
voltage differential, or:
Shutdown Mode
The TC57 enters a low power shutdown mode when the
shutdown input (SHDN) is high. During shutdown, the regu-
lator is disabled, the output capacitor is discharged through
the load, and supply current to the TC57 decreases to less
than1µA.NormaloperationresumeswhenSHDNisbrought
low. If the shutdown mode is not used, SHDN should be tied
to VIN.
PD = ILOAD(MAX) x (VIN(MAX) –VOUT(min)
)
Equation 2.
The ideal transistor has a minimum hFE of 100, and a
VCE(SAT) oflessthan0.6Vatfulloutputcurrent. Forexample,
the Zetex FZT749 has an hFE of 170 at a collector current of
1A, and a guaranteed VCE(SAT) of 0.3V at a base current of
100 mA. It is packaged in a SOT223 and is recommended
for use with the TC57. Other transistors are also suitable,
depending on the required input and output voltages and
output current (Table 2a).
