DETAILED DESCRIPTION The TC59 is a low quiescent current, precision fixed negative output voltage LDO. Unlike bipolar linear regulators, the TC59 supply current does not increase proportionally with load current. 3.1 Output Capacitor A minimum of 1F tantalum output capacitor is required. The requirements for the output capacitor are an equivalent series resistance (esr) greater than 0.1 and less than 5, with a self-resonant frequency greater than 1MHz. To improve supply noise rejection and transient response, larger output capacitors can be used. Care should be taken when increasing COUT, that the input impedance is not high enough to cause high input impedance oscillation.  2001-2012 Microchip Technology Inc. 3.2 Input Capacitor A 1F input capacitor is recommended for most applications when the input impedance is on the order of 10. When operating off of a battery input, or there is a large distance from the input source to the LDO, larger input capacitance may be required for stability. When large values of output capacitance are used, the input capacitance should be increased to prevent high source impedance oscillations. DS21438C-page 3 TC59 4.0 THERMAL CONSIDERATIONS 4.1 Power Dissipation EQUATION 4-3: PTOTAL = PD (Pass Device) + PD (Bias) The amount of power dissipated internal to the low drop out linear regulator is the sum of the power dissipation within the linear pass device (P-Channel MOSFET), and the quiescent current required to bias the internal reference and error amplifier. The internal linear pass device power dissipation is calculated multiplying the voltage across the linear device times the current through the device. The input and output voltages are negative for the TC59. The power dissipation is calculated using the absolute value of the voltage difference between the input and output voltage. For the TC59, the internal quiescent bias current is so low (3A typical), the PD (Bias) term of the power dissipation equation can be ignored. The maximum power dissipation can be estimated by using the maximum input voltage and the minimum output voltage to obtain a maximum voltage differential between input and output and multiplying the maximum voltage differential by the maximum output current. EQUATION 4-4: PMAX = (VIN (MAX) – VOUT (MIN)) X IOUT (MAX) TABLE 4-1: MAXIMUM POWER DISSIPATION Package Type Maximum Power Dissipation SOT-23-3 150mW For example, given the following conditions: VIN = -7.0V ±5% VOUT = -5.0V ±2% IOUT = 1mA to 40mA TAMBIENT (MAX) = 55°C EQUATION 4-1: PD (Pass Device) = (VIN – VOUT) X IOUT The internal power dissipation as a result of the bias current for the LDO internal reference and error amplifier is calculated by multiplying the ground or quiescent current times the input voltage. EQUATION 4-2: PD (Bias) = VIN X IGND The total internal power dissipation is the sum of Equation 4-1 and Equation 4-2. PMAX = (7V X (1.05) – (5.0V X 0.98)) X 40mA PMAX = 98.0 milli-Watts To determine the junction temperature of the device, the thermal resistance from junction to air must be known. The SOT-23-3 RJA is estimated to be approximately 359°C/W when mounted on a 4-layer board. The RJA will vary with physical layout, airflow and other application specific conditions. The device junction temperature is determined by calculating the junction temperature rise above ambient, then adding the rise to the ambient temperature. EQUATION 4-5: JUNCTION TEMPERATURE (SOT-23 EXAMPLE) TJUNCTION = PD (MAX) X RJA + TAMBIENT TJUNCTION = 98.0 milli-Watts X 359°C/W + 55°C TJUNCTION = 90.2°C DS21438C-page 4  2001-2012 Microchip Technology Inc. TC59 5.0 Note: TYPICAL CHARACTERISTICS The graphs and tables provided following this note are a statistical summary based on a limited number of samples and are provided for informational purposes only.

DS21438C-page17 TC59 NOTES: DS21438C-page18  2001-2012 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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act. Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications.
