Designed specifically for battery-operated systems, the devices’ CMOS construction minimizes ground current, extending battery life. Total supply current is typically 50 µA at full load (20 to 60 times lower than in bipolar regulators). Applications • • • • • • • Battery Operated Systems Portable Computers Medical Instruments Instrumentation Cellular/GSM/PHS Phones Linear Post-Regulators for SMPS Pagers The TC1054, TC1055 and TC1186 are stable with an output capacitor of only 1 µF, and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. For higher output current regulators, please refer to the TC1173 (IOUT = 300 mA) data sheet (DS21632). Typical Application VIN 1 2 3 Package Type VOUT 5 VIN TC1054 TC1055 TC1186 GND SHDN The devices’ key features include low noise operation, low dropout voltage – typically 85 mV (TC1054), 180 mV (TC1055) and 270 mV (TC1186) at full load — and fast response to step changes in load. An error output (ERROR) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). ERROR can be used as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.5 µA (maximum), with both VOUT and ERROR disabled when the shutdown input is low. The devices incorporate both overtemperature and over-current protection.

If there is a large distance between the input supply and the LDO regulator, some input capacitance is necessary for proper operation. A 1 µF capacitor connected from VIN to ground is recommended for most applications. 3.3 The regulator is fully enabled when a logic-high is applied to SHDN. The regulator enters shutdown when a logic-low is applied to SHDN. During shutdown, output voltage falls to zero, ERROR is open-circuited and supply current is reduced to 0.5 µA (maximum). 3.4 3.2 Ground Terminal (GND) Connect the unregulated input supply ground return to GND.

TC1054/TC1055/TC1186 4.0 DETAILED DESCRIPTION The TC1054, TC1055 and TC1186 are precision fixed output voltage regulators (If an adjustable version is desired, please see the TC1070/TC1071/TC1187 data sheet (DS21353)). Unlike bipolar regulators, the TC1054, TC1055 and TC1186 supply current does not increase with load current. Figure 4-1 shows a typical application circuit, where the regulator is enabled any time the shutdown input (SHDN) is at or above VIH, and shutdown (disabled) when SHDN is at or below VIL. SHDN may be controlled by a CMOS logic gate or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in Shutdown, supply current decreases to 0.05 µA (typical), VOUT falls to zero volts, and ERROR is opencircuited. + + 1 µF Battery VIN VOUT TC1054 TC1055 TC1186 + VOUT 1 µF C1 4.1 ERROR is driven low whenever VOUT falls out of regulation by more than -5% (typical). This condition may be caused by low input voltage, output current limiting or thermal limiting. The ERROR threshold is 5% below rated VOUT, regardless of the programmed output voltage value (e.g. ERROR = VOL at 4.75V (typical) for a 5.0V regulator and 2.85V (typical) for a 3.0V regulator). ERROR output operation is shown in Figure 4-2. Note that ERROR is active when VOUT falls to VTH and inactive when VOUT rises above VTH by VHYS. As shown in Figure 4-1, ERROR can be used either as a battery low flag or as a processor RESET signal (with the addition of timing capacitor C2). R1 x C2 should be chosen to maintain ERROR below VIH of the processor RESET input for at least 200 ms to allow time for the system to stabilize. Pull-up resistor R1 can be tied to VOUT, VIN or any other voltage less than (VIN + 0.3V). VOUT GND SHDN HYSTERESIS (VH) VTH ERROR Shutdown Control (to CMOS Logic or Tie to VIN if unused) C2 Required Only if ERROR is used as a Processor RESET Signal (see Text) FIGURE 4-1: ERROR Open-Drain Output V+ R1 1 MΩ BATTLOW or RESET 0.2 µF C2 Typical Application Circuit. 2002-2012 Microchip Technology Inc. tDELAY ERROR VIH VOL FIGURE 4-2: 4.2 Error Output Operation. Output Capacitor A 1 µF (minimum) capacitor from VOUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1 and less than 10.0, with a resonant frequency above 1 MHz. A 1 µF capacitor should be connected from VIN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used (since many aluminum electrolytic capacitors freeze at approximately -30°C, solid tantalums are recommended for applications operating below -25°C). When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques. DS21350E-page 9 TC1054/TC1055/TC1186 5.0 THERMAL CONSIDERATIONS 5.1 Thermal Shutdown Integrated thermal protection circuitry shuts the regulator off when die temperature exceeds +160°C. The regulator remains off until the die temperature drops to approximately +150°C. 5.2 Power Dissipation The amount of power the regulator dissipates is primarily a function of input voltage, output voltage and output current. The following equation is used to calculate worst-case actual power dissipation: EQUATION 5-1: Equation 5-1 can be used in conjunction with Equation 5-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.0V +5% VOUTMIN = 2.7V – 2.5% ILOADMAX = 40 mA TJMAX = +125°C TAMAX = +55°C Find: PD V INMAX – VOUTMIN ILOADMAX = 3.0 1.05 – 2.7 0.975 40 10 Where: PD = Worst-case actual power dissipation VOUTmin = Minimum regulator output voltage EQUATION 5-2: T JMAX – T AMAX P DMAX = ------------------------------------------- JA Where all terms are previously defined. DS21350E-page 10 -3 = 20.7mW Maximum allowable power dissipation: T JMAX – T AMAX PDMAX = -------------------------------------------- ILOADmax = Maximum output (load) current The maximum allowable power dissipation (Equation 5-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) and the thermal resistance from junction-to-air (JA). The 5-Pin SOT-23 package has a JA of approximately 220°C/Watt. Actual power dissipation Maximum allowable dissipation Actual power dissipation: PD V INMAX – VOUTMIN ILOADMAX VINmax = Maximum voltage on VIN 1. 2. JA 125 – 55 = ------------------------220 = 318mW In this example, the TC1054 dissipates a maximum of 20.7 mW; below the allowable limit of 318 mW. In a similar manner, Equation 5-1 and Equation 5-2 can be used to calculate maximum current and/or input voltage limits. 5.3 Layout Considerations The primary path of heat conduction out of the package is via the package leads. Layouts having a ground plane, wide traces at the pads and wide power supply bus lines, combine to lower θJA and increase the maximum allowable power dissipation limit. 2002-2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
