TPL720 Series
400 mA output, 1 µA Ultra-Low Quiescent Current LDO
Detailed Description
Overview
The TPL720 series products are CMOS process low Iq linear regulators with ultra-low quiescent power consumption. The TPL720
series products support maximum 400mA output current, with typically only 1.4 µA quiescent current. TPL720 series products are
stable with low-ESR small ceramic output capacitor from 2.2μF to 10μF. The TPL720 series products are available in fixed voltage
versions of 1V, 1.2 V, 1.8 V, 2.5 V, 2.8 V, 3 V, 3.3 V and 3.6 V.

TPL720 Series
400 mA output, 1 µA Ultra-Low Quiescent Current LDO
Feature Description
Enable (4-/5-Pin Package Only)
The enable pin (EN) is active high. Connect this pin to the GPIO of an external processor or digital logic control circuit to enable and
disable the device. Or connect this pin to the IN pin for self-bias applications.
Under-voltage Lockout (UVLO)
The TPL720 series use an under-voltage lockout circuit (UVLO = 1.8 V) to keep the output shut off until the internal circuitry operates
properly.
Regulated Output Voltage
The TPL720 series are available in fixed voltage versions of 1V, 1.2 V, 1.8 V, 2.5 V, 2.8 V, 3 V, 3.3 V and 3.6 V. When the input voltage
is higher than VOUT(NOM) + VDO or 2.4V, output pin is the regulated output based on the selected voltage version. When the input
voltage falls below VOUT(NOM) + VDO or 2.4V, output pin tracks the input voltage minus the dropout voltage based on the load current.
When the input voltage drops below UVLO threshold, the output keeps shut off.
Current Limit
The TPL720 series integrate an internal current limit that helps to protect the regulator during fault conditions. When the output is
overloaded or shorted to ground, the LDO supplies output current with limited value to prevent the regulator from damage. Output
voltage is not regulated when the device is in current limit mode, and the value is VOUT = ICL × RLOAD.
Thermal Shutdown
During normal operation, LDO junction temperature should not exceed 125°C. When the junction temperature exceeds the thermal
shutdown threshold, the LDO shut down the output immediately. Until when the junction temperature falls below the thermal shutdown
threshold minus thermal shutdown hysteresis, the output turns on again.

Application and Implementation
NOTE
Information in the following applications sections is not part of the 3PEAK’s component specification and 3PEAK does
not warrant its accuracy or completeness. 3PEAK’s customers are responsible for determining suitability of
components for their purposes. Customers should validate and test their design implementation to confirm system
functionality.
Application Information
The TPL720 devices are a series of 400 mA high PSRR, low-dropout linear regulator with low quiescent current. The following

Input Capacitor and Output Capacitor
3PEAK recommends adding a 1 μF or greater capacitor with a 0.1 μF bypass capacitor in parallel at IN pin to keep the input voltage
stable. The voltage rating of the capacitors must be greater than the maximum input voltage.
To ensure loop stability, the TPL720 series requires an output capacitor with a minimum effective capacitance value of 2.2 μF. 3PEAK
recommends selecting a X5R- or X7R-type 4.7 μF or larger ceramic capacitor with low ESR over temperature.
Both input capacitors and output capacitors must be placed as close to the device pins as possible.
Power Dissipation
During normal operation, LDO junction temperature should not exceed 125°C. Using below equations to calculate the power
dissipation and estimate the junction temperature.
The power dissipation can be calculated using Equation 1.
PD = ( VIN − VOUT ) IOUT + VIN IGND
(1)
The junction temperature can be estimated using Equation 2. θJA is the junction-to-ambient thermal resistance (See Section Thermal
Information).
TJ = TA + PD JA

Layout Requirements
•
Both input capacitors and output capacitors must be placed as close to the device pins as possible.
•
It is recommended to bypass the input pin to ground with a 0.1 μF bypass capacitor. The loop area formed by the bypass
capacitor connection, IN pin and the GND pin of the system must be as small as possible.
•
It is recommended to use wide trace lengths or thick copper weight to minimize I×R drop and heat dissipation.
