Package Type General Description The TC59 is a low dropout, negative output voltage regulator designed specifically for battery-operated systems. Its full CMOS construction eliminates the wasted ground current typical of bipolar LDOs. This reduced supply current significantly extends battery life, particularly when the TC59 is operated in dropout. Other TC59 key features include low supply current (typically 3.0 µA) and low dropout operation (typically 120mV at 50mA). The TC59 is packaged in a small 3-Pin SOT-23A package.

3.0 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 µF tantalum output capacitor is required. The requirements for the output capacitor are an equivalent series resistance (esr) greater than 0.1 Ω and less than 5 Ω, 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 C OUT, that the input impedance is not high enough to cause high input impedance oscillation.
3.2 Input Capacitor
A1 µF input capacitor is recommended for most applications when the input impedance is on the order of 10Ω. 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. Pin No. (3-Pin SOT-23A) Symbol Description 1V OUT Regulated voltage output. 2V IN Supply voltage input. 3V SS Ground.

4.0 THERMAL CONSIDERATIONS
4.1 Power Dissipation
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. TABLE 4-1: MAXIMUM POWER DISSIPATION EQUATION 4-1: 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: The total internal power dissipation is the sum of Equation 4-1 and Equation 4-2. EQUATION 4-3: For the TC59, the internal quiescent bias current is so low (3 µAt y p i c a l ) ,t h eP D (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: For example, given the following conditions: VIN =- 7 . 0 V ± 5 % VOUT =- 5 . 0 V ± 2 % IOUT = 1mA to 40mA TAMBIENT (MAX)= 55°C 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 θJA i se s t i m a t e dt ob e approximately 359°C/W when mounted on a 4-layer board. The R θJA 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) Package Type Maximum Power Dissipation SOT-23-3 150mW PD (Pass Device) = (VIN –V OUT)XI OUT PD (Bias) = VIN XI GND PTOTAL =P D (Pass Device) + PD (Bias) PMAX =( VIN (MAX) –V OUT (MIN))XI OUT (MAX) TJUNCTION =P D (MAX) XR θJA +T AMBIENT TJUNCTION = 98.0 milli-Watts X 359°C/W + 55°C TJUNCTION = 90.2°C
