General Description

The TC1016 is a high-accuracy (typically ±0.5%),

CMOS upgrade for bipolar low dropout regulators

(LDOs). The TC1016 is offered in both the SC-70 and

SOT-23 packages. The SC-70 package represents a

50% footprint reduction versus the popular SOT-23

package.

Developed specifically for battery-powered systems,

the device’s CMOS construction consumes only 53 µA

typical supply current over the entire 80 mA operating

load range. This can be as much as 60 times less than

the quiescent operating current consumed by bipolar

LDOs.

With small-space requirements and cost in mind, the

TC1016 was developed to be stable over the entire

input voltage and output current operating range using

low value (1 µF ceramic), low Equivalent Series

Resistance (ESR) output capacitors. Additional

integrated features (such as shutdown, overcurrent

and overtemperature protection) further reduce board

space and cost of the entire voltage-regulating

application.

Key performance parameters for the TC1016 are low

drop out voltage (150 mV (typ.) at 80 mA output

current), low supply current while shutdown (0.05 µA

typical) and fast stable response to sudden input

voltage and load changes.

TC1016 4.0 DETAILED DESCRIPTION MOSFET is turned on. If the internal power dissipation is still high enough for the junction to rise to 160°C, it will again shut off and cool. The maximum operating junction temperature of the device is 125°C. Steadystate operation at or near the 160°C overtemperature point can lead to permanent damage of the device. The TC1016 is a precision, fixed-output, linear voltage regulator. The internal linear pass element is a Pchannel MOSFET.

TC1016 4.1 Input Capacitor 4.3 Low input source impedance is necessary for the LDO to operate properly. When operating from batteries, or in applications with long lead length (> 10") between the input source and the LDO, some input capacitance is required. A minimum of 0.1 µF is recommended for most applications and the capacitor should be placed as close to the input of the LDO as is practical.

TC1016 5.0 THERMAL CONSIDERATIONS 5.1 Thermal Shutdown Integrated thermal-protection circuitry shuts the regulator off when die temperature exceeds approximately 160°C. The regulator remains off until the die temperature drops to approximately 150°C. Given the following example: VOUT = 2.8V ±2.5% ILOAD = 60 mA (output current) Find: Power Dissipation Internal power dissipation: P DMAX = ( V IN_MAX – V OUT_MIN ) × ILOAD The TC1016 is available in the SC-70 package.
