It is an ideal regulator for sub 1.2-V 23 DSP core voltage supplies and is equally suited IO = 10 µA 21 for similar applications with other low-voltage processors and controllers. SOT-23 packaging 19 and the high-efficiency that results from the regulator’s ultralow power operation make the 17 TPS76201 especially useful in handheld and 15 portable battery applications. This regulator −40 −25 −10 5 20 35 50 65 80 95 110 125 features low dropout voltages and ultralow TJ − Junction Temperature − °C quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS76201 is ideal for micropower operations and where board space is at a premium. A combination of new circuit design and process innovation has enabled the usual PNP pass transistor to be replaced by a PMOS pass element. Since the PMOS pass element is a voltage-driven device, the quiescent current is ultralow (30 µA maximum) and is stable over the entire range of output load current (10 µA to 100 mA). Intended for use in portable systems such as laptops and cellular phones, the ultralow-power operation results in a significant increase in the system battery operating life. The TPS76201 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 µA typical at TJ = 25°C. The TPS76201 is offered in an adjustable version (programmable over the range of 0.7 V to 5.5 V).

 SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION The TPS76201 low-dropout (LDO) regulator has been optimized for use in battery-operated equipment including, but not limited to, the sub 1.2-V DSP core voltage supplies. It features low quiescent current (23 µA nominally) and enable inputs to reduce supply currents to 1 µA when the regulators are turned off. A typical application circuit is shown in Figure 17. TPS76201 1 VI IN 5 OUT C1 1 µF 3 EN FB VO 4 + GND 2 4.7 µF ESR = 0.5 Ω Figure 17. Typical Application Circuit external capacitor requirements Although not required, a 0.047-µF or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS76201, is recommended to improve transient response and noise rejection. A higher-value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inches from the power source. Like all low dropout regulators, the TPS76201 requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance is 4.7 µF. The ESR (equivalent series resistance) of the capacitor should be between 0.3 Ω and 1.5 Ω. to ensure stability. Capacitor values larger than 4.7 µF are acceptable, and allow the use of smaller ESR values. Capacitances less than 4.7 µF are not recommended because they require careful selection of ESR to ensure stability. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described above. Most of the commercially available 4.7 µF surface-mount solid tantalum capacitors, including devices from Sprague, Kemet, and Nichico, meet the ESR requirements stated above. Multilayer ceramic capacitors may have very small equivalent series resistances and may thus require the addition of a low value series resistor to ensure stability. CAPACITOR SELECTION PART NO.

 SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION output voltage programming The output voltage of the TPS76201 adjustable regulator is programmed using an external resistor divider as shown in Figure 18.

 SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION power dissipation and junction temperature Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature should be restricted to 125°C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or equal to PD(max). The maximum-power-dissipation limit is determined using the following equation: P T max * T A + J D(max) R qJA Where: TJmax is the maximum allowable junction temperature. RθJA is the thermal resistance junction-to-ambient for the package, see the dissipation rating table. TA is the ambient temperature. The regulator dissipation is calculated using: P D ǒ Ǔ + V *V I O I O Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the thermal protection circuit. regulator protection The TPS76201 PMOS-pass transistor has a built-in back diode that conducts reverse current when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be appropriate. The TPS76201 features internal current limiting and thermal protection. During normal operation, the TPS76201 limits output current to approximately 350 mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds approximately 165°C, thermal-protection circuitry shuts it down. Once the device has cooled down to below approximately 140°C, regulator operation resumes. www.ti.com 9 PACKAGE OPTION ADDENDUM www.ti.com 19-Oct-2022 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan (2) Lead finish/ Ball material MSL Peak Temp Op Temp (°C) Device Marking (3) Samples (4/5) (6) TPS76201DBVR ACTIVE SOT-23 DBV 5 3000 RoHS & Green NIPDAU Level-1-260C-UNLIM -40 to 125 PFUI Samples TPS76201DBVRG4 ACTIVE SOT-23 DBV 5 3000 RoHS & Green NIPDAU Level-1-260C-UNLIM -40 to 125 PFUI Samples TPS76201DBVT ACTIVE SOT-23 DBV 5 250 RoHS & Green NIPDAU Level-1-260C-UNLIM -40 to 125 PFUI Samples (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
