CM3002 Micropower 1.0A Low Dropout CMOS Regulators Features Product Description • The CM3002 family of regulators are very low dropout regulators that deliver up to 1.0A of load current at a fixed voltage output. Input and output voltage options for the CM3002 family devices are presented in Table 1. • • • • • • • • • • Regulated output options: 1.5, 1.8, 2.5 and 3.3 volts 1.0A output current Operates from 3.3V supply (5.0V for CM3002-33) Very low dropout voltage on CM3002-33 products (500mV@1A) Enable Output Control for power-up sequencing Low quiescent operating current (< 600µA typical) Current limit protection Thermal overload protection Reverse voltage protection Available in thermally-enhanced SOIC-8 and MSOP-8 (CM3002-33MA/MF) packages Lead-free versions available Applications • • • Low Voltage "Core" Processors Peripheral Adapter Cards Portable/Battery-Powered Devices Table 1: CM3002 Regulator Family PRODUCT INPUT VOLTAGE OUTPUT VOLTAGE CM3002-15SA/SF 3.3V 1.5V CM3002-18SA/SF 3.3V 1.8V CM3002-25SA/SF 3.3V 2.5V CM3002-33SA/SF 5.0V or 3.3V 3.3V CM3002-33MA/MF 5.0V or 3.3V 3.3V Operating from a single input supply, these devices are ideally suited for powering low voltage “core” processors, especially where a 3.3V source is already available. These regulators feature a dedicated control input (EN, Active High) for power-up sequencing flexibility. When this input is taken low, the regulator output is disabled. In this state, the supply current will drop to a low level to ensure all the internal control circuitry still remains active. This provides excellent start-up response whenever the device comes out of shutdown. The CM3002 family of regulators is fully protected, offering both overload current limiting and high temperature thermal shutdown. Housed in space saving thermally-enhanced SOIC-8 and MSOP-8 (CM3002-33MA/ MF) packages, these devices ensure maximum junction-to-ambient power dissipation. The CM3002 is available with optional lead-free finishing.

PIN DESCRIPTIONS PIN(S) NAME 1 EN DESCRIPTION A logic input control to enable the regulator output. When EN is asserted (logic high), it allows output regulation to commence. When EN is deasserted (logic low), the regulator pass transistor (Nchannel MOSFET) is forced into a high impedance mode. All other internal circuitry is unaffected by the state of the EN input and will always remain powered whenever VCC is present. An internal pull-up current (2µA) from VCC must be overdriven in order to apply a Logic Low to the EN control input. The EN control input is intended to be used for power-up sequencing. 2 VCC The input power supply for the regulator. If this input is within a few inches of the main supply filter, a capacitor may not be necessary. Otherwise an input filter capacitor of approximately 1uF to 10uF will ensure adequate filtering. 3 VOUT The regulator voltage output used to power the load. A nominal output capacitor of 10uF is sufficient to minimize any transient disturbances under normal operating conditions. Additional output capacitance can be used to further improve transient load response. 4 N.C. These pins have no connection to the internal device. To provide additional thermal performance, these pins can be connected directly to the PC board GND plane. 5,6,7,8 GND The negative reference for all voltages.

The first path is the junction to the case (θ JC) which is defined by the package style, and the second path is case to ambient (θ CA) thermal resistance which is dependent on board layout. The final operating junction temperature for any set of conditions can be estimated by the following thermal equation: TJUNC = TAMB + PD ∗ (θJC) + PD ∗ (θCA) = TAMB + PD ∗ (θ JA) The CM3002 family uses thermally enhanced SOIC and MSOP packages where all the GND pins (5 through 8) are integral to the leadframe. When this package is mounted on a double sided printed circuit board with two square inches of copper allocated for “heat spreading”, the resulting θJA is about 50° C/W for the SOIC package and 70° C/W for the MSOP package. Based on a maximum power dissipation of 0.8W (Load x Vin-Vout = 1.0A x [3.3V-2.5V]) with an ambient of 70° C, the resulting junction temperature for a SOICpackaged device will be: Thermal characteristics were measured using a double sided board with two square inches of copper area connected to the GND pins for “heat spreading”. Measurements showing performance up to a junction temperature of 125° C are presented in Figure 1, Figure 2, Figure 3 and Figure 4. They were performed under light load conditions (5mA); this allows the ambient temperature to be representative of the internal junction temperature. Note: The use of multi-layer board construction with separate ground and power planes will further enhance the overall thermal performance. In the event of no copper area being dedicated for heat spreading, a multi-layer board construction using only the minimum size pad layout will typically provide a CM3002 device packaged in a SOIC package with an overall θ JA of 50° C/W, which allows up to 0.8W to be dissipated safely. Please consult CAMD Technical Support for assistance with thermal analysis of the CM3002 family of regulators with respect to a specific application.
